Local database for windows xp application - c#

I'm writing an application for a bunch of xp users. My application should be able to run on the minimum requirements (the least possible, the users use old old computers).
At first I started developing on VS 2012 and .Net 3.5 + SqlLocalDB. Later I found out that xp does not support SqlLocalDB, then I switched to SqlExpress and I still can not install my application on xp (even though if it worked, it was a little heavy cause you need 20 minutes to install it, not a one click solution), and it does not give a proper error message, it just says this application is not a valid win32 application.
I am even switching to VS 2010 to make things clearer in my head, can't get where the problem is.
By the way I am using LinqToSql technology so I need the DB to be Sql, even more on the other versions (.Net 4.0 and SqlLocalDB) I can use .mdf database files, so I would rather not to go around Access database.
Anyway, this is the case : I need to run an application with .Net 3.5 and a Local Database, I want the installation to be as easy as a one click setup.
I am confused. Please share your knowlege with me.

Have you checked SQLite ?
Seems to be good candidate.

Well you need .NET Framework 4.0.2 (or above) + Windows Vista SP2 (or above) to use SqlLocalDb so you can not build an application with .NET 3.5 & LocalDb for windows XP.
Try using .NET 3.5 + SQL Server Compact 4.0 sp1 instead

Deploy C# application with Access Database, without access instalation

Context
For a bit more context, the company I work for made an Access vb.net application that runs inside MS Access. They wanted to upgrade and create a C# WPF frontend for it. This works great except for the fact that when I installed the application and downloaded the [dummyDB].accdb (32-bits 2016) the application immediatly broke with the error :
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.
I then installed the 2010 AccessDataBaseEngine from Microsoft and a new error apeared:
This Database file requires a newer version of Access
Naturally I went back to Microsoft, downloaded and installed the 2016 x64 (my system is 64-bits) and tried again.
Sadly we we're back to the first error. So i tried to install the 2016 32-bits AccessDataBaseEngine but ran into the problem that I had already installed 64-bits office products. (I also uninstalled all the previous 32-bit AccessDataseEngines)
We of course don't want users to reinstall all their Office products just to use our application.
Question
Is there a NugetPackage of somesort that we could use so the customer can interact with the AccessDatabase out of the box?
If not, is there anyway to make it so they wouldn't have to reinstall all of their Office products?
ps. Different DataBase files 32-bit and 64-bit for users is also not an option because different users with most likely different systems will have to access the same database file.
I don't know if I'm being completely oblivious here, but any help would be greatly appreciated
Application info:
WPF application (.Net Framework 4.7.2)
Build Target : anyCPU
Is there a NugetPackage of somesort that we could use so the customer can interact with the AccessDatabase out of the box
No, not as far as I know.
If not, is there anyway to make it so they wouldn't have to reinstall all of their Office products?
You could write an wrapper that handles both 32 and 64 bit versions of the access driver. I.e. if the installed driver is the same platform as your program you can just continue as usual. If it is another platform you need to start a new process with the correct platform, and delegate all the database work to this process. If your process is anyCPU and is run on 64-bit windows the actual platform will depend on the "prefer 32-bit" flag.
Another alternative is to build both 32 and 64 bit versions of your entire application and run the one matching the office installation. This might be easier, but might not work if you have other platform specific dependencies.
This all assumes that office is already installed, if it is not you can just deploy the stand alone ace driver (i.e. AccessDataBaseEngine) with the correct bittness. The database file itself is platform agnostic and can be accessed by either 32 or 64 bit processes. It is the driver that needs to be of the correct version.
Note that Access is kind of difficult to work with and rather error prone. If this product is intended to be long lived I would suggest migrating to something better sooner rather than later. SqlLite is a popular embedded database engine that could be an alternative.

Is it possible to run a program developed for Windows Embedded Compact 7 on Windows Mobile 6.5?

I have tried searching for this answer and have had no luck.
Any information would be useful.
Windows Mobile 6.5 was released in 2008 based on CE 5.2. Windows Embedded Compact 7 was released in 2011 and is CE 7.
If the application is developed targeting .Net Compact Framework 3.5 on Compact 7 then I think it will still run on 6.5.
If it was developed as native on Compact 7 then it may not run on Mobile 6.5 depending on APIs it uses. This answer says it can work. Applications going the other way are more likely to work.
Since you added C# I suppose that you are talking about a managed app.
To run it you need the right version of the compact framework or a newer one on your device.
Latest version supported on WM6.5 should be 3.5, I don't remember if it was part of the OS or if you needed to install it separately, here's the download link:
https://www.microsoft.com/en-us/download/details.aspx?id=65
If your app uses also native code things may be a little more complicated.
CE 7 is binary compatible with older versions (WM6.5 is based on CE5), so those binary components may run on CE5 too. On the other side, new APIs have been added in CE6 and CE7 and this (or just the fact that they have been rebuilt using new SDKs) may prevent those things from running on that device.
It may also happen that a managed app invokes some APIs that are not supported on that specific device (this may depend from OS version but also from the component the manufacturer decided to include in the OS image for that specific device).
If you have source code you may be able to fix those issue.
The only thing you can do is try and see what errors you get (if any). It's not granted that it will run, it's not granted that it won't run.

WPF Application designed in VS 2012 won't run on Windows 7 machine

I've designed a WPF C# application using Visual Studio 2012. The application, which is simple enough, runs fine on my Windows 8 machine using the ClickOnce deployment method. The datagrid displays the content from a SQL Server database and performs all of it's other functions just as I've designed it to, but when I attempt to install it on a Windows 7 machine it immediately crashes and I'm not sure why. The Windows 7 computer I'm trying to install the application on has .NET 4.5 running on it, but is there anything else that computer needs to have installed on it in order to run applications developed with VS 2012. This is my first attempt to install an application developed with VS 2012 on a Windows 7 machine, so I'm not sure if there's another step that I'm missing here. Any help you guys can provide would be greatly appreciated. Thank you.
The message you stated "The application has stopped working and that if Microsoft has a solution..." is an indicator of one of the following:
The Framework is disabled; though 4.5 is installed several root instances are built on the foundation which are apart of Framework 2.0. This particular Framework can cause issues for 3.0, 3.5, 4.0, and even 4.5.
The System.EnterpriseServices.dll is damaged in the Framework. Which needs to be connected back to the Global Assembly Cache (GAC).
And another common issue is the machine.config file log in the Framework Folder can be corrupt and needs to be replaced with a valid one.
There are others that can occur within the System Policy Folder as well, which may require you to use the .Net Cleanup Tool and reinstall the Framework. But before you do any troubleshooting you should go to the Event Viewer and get details of what is going on.
Try these steps first for me:
Windows Key + R
When the run prompt appears type: appwiz.cpl
Go to the left hand side: Turn Windows Features On or Off
Turn Framework 3.5 on if it isn't already; if it is already on go to Step 5.
Turn off the Framework; then reboot.
Once rebooted follow steps 1-4 again.
Now at this point I would suggest trying the application again. If it fails try this:
Open Start
Type 'cmd' in Search
Right Click and Run as an Administrator
Type %windir%\Microsoft.Net\Framework\v2.0.50727\ngen.exe update
Then type: sfc /scannow
The Native Regeneration tool will try to repair the Framework back to a factory state; the System-File-Checker will attempt to fix any errors indicated in Windows. If it can't it will say 'it found integrity violations'.
Those are the steps I would do for general support; but you really should try and locate an error message. As the Framework can become a huge ordeal to cleanup and fix. If you provide more information I will revise my response to help address it.
Hopefully that helps.

Cant install .NET application in Clients PC

My client's PC runs Windows 7 Ultimate with .netframework 4 client profile. I am unable to install my application developed in VS2008. I tried uninstalling .NET Framework 4 From his PC and running the Clean up tool provided by Microsoft. But still I am unable to install it successfully. It provides Error 1001.
I tried running the program as administrator. I also tried to Turn on .net 3.5 feature from add or remove program.
Thanks in advance. :)
Edit:
The error what i get is shown here.
Furthermore,
I have confirmed that it is a 32bit processor and i run x86 release version of setup
The application is developed in a Windows 7 OS with .NET Framework 3.5
I have installed this application in 7 PCs which have .NET 3.5 installed in them and having OS Windows XP,Vista and Windows 7; and all are working fine.
In clients PC, when I try to install .NET 3.5 again, the installer starts but then it disappears suddenly without doing anything
I have tried turning on .NET 3.5 framework feature from control panel> Program and Features.
I have tried running the program as Administrator
I have tried setting the application setup in Windows XP and Vista compatible mode.
But still the issue persists.
Thanks :)
#Niraj.. hope you recognize me.. :)
Well, I think the issue is with your installer. Something in your package settings is conflicting with the environment at your client's computer. With the error message that you posted, it looks like there is some dependency on some assembly which isnt available to the installer, and hence its failing. This might include version number mismatches too.
You should also look at this question, which talks about an issue similar to yours.
or try using FusLogvw.exe to check which assemblies fail to load at runtime.
As you said you have only .net framework 4 client profile which is a subset of the .NET Framework 4 and is optimized for client applications. Please make sure that everything needed for your new application is included in client profile version. Also it is possible that your application installer requires .NET Frw 3.5 as a dependency. Anyway as already said by Henk no need to do anything with .NET Frw 4 just install 3.5.
There is an exception raised during the installation, and you should as it wished to collect MSI debug log and other necessary information to troubleshoot.
I don't think .NET 4 is the root cause. Otherwise, you should already install this app after uninstallation of .NET 4.
in my opinion
be sure that you not run X64 application in X86 based computer
trying to run them in compatibility mode for OS depend on which OS you used in client system
check the prerequested component are installed or not in client system.
you show the problem 1001 in snapshot so you can Read the log for more information about the setup you trying to install on client side.
your setup forced client system to load a specific type during the installation and type not exactly load as setup want so they give you a exception called "LoaderException"
for more information start googling may be it solved your problem
http://www.google.co.in/search?sourceid=chrome&ie=UTF-8&q=loaderexception+in+.net&qscrl=1
I got it finally...nothing was stopping my application but Crystal Reports.
We forgot to include Crystal Reports Basic as a prerequisite.
Thank you guys for the efforts taken. :)

How to make software developed in WinForms .NET 3.5 with SQL Express portable

i found that its really pain to create setup and deployment packages for windows xp/vista/7
so my question is can i make my application portable with any third party tool such as thin app ?
my application requires dot net 3.5 framework and sql express 05 installed i want to put it on usb drive and user can execute it directly from usb drive without any setup and deployment, if there any other ways to achieve portability for software please let me know?
thanks !
In order to check if .Net 3.5 and sql express is installed you can check if they are registred in the registry.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\MSSQLServer\CurrentVersion - CurrentVersion
But you cannot check this with your 3.5 compiled assembly, so you need a non-dotnet application to do it, like a setup program.
Either you have to create a launcher in something like c++, or you could create a vb script launcher which checks the prerequisites before launching your .net app.
Neither SQL Express nor the .NET Framework will not run without being installed on the local hard disk.
Source for SQL Express: http://social.msdn.microsoft.com/Forums/en-US/sqlsetupandupgrade/thread/fc729d31-8a0b-4156-ab75-4fec652a438b.
#Mikael already told the trick for .NET detection which you should take a look at.
I just want to add that for portable applications, you should use SQL Server Compact edition instead of Express,
