I have a perfectly working windows forms C# .NET 4 application that uses a SQLite3 database file to store data and display forms.
When I deploy my app on any machine other then the dev machine, I get an exception thrown and it's message is "Could not load assembly System.Data.SQLite.dll or one of its dependencies. The specified module could not be found."
The System.Data.SQLite.dll reference in the project is set to Copy Local = True. Also, I tried manually loading the assembly with Assembly.LoadFile. The dll is placed in the output directory. I also tried setting the platform target to Any CPU as well as x86, no difference. All machines I am working with are 32-bit. What is the issue here? Why is my application trying to load the assembly and can't find it?
Thanks!
I had the same problem after publishing my program to a separate computer. Installing Microsoft Visual C++ 2010 Redistributable Package (x86) on the separate computer fixed the problem.
Note: the separate computer already had Microsoft Visual C++ 2010 Redistributable Package (x64) installed, the x86 version was needed.
'System.Data.SQLite.dll" requires "msvcr100.dll" which is one of it's Dependencies. This will be available only if you installed latest "Microsoft Visual C++ Redistributable" or any other product which internally provides this.
For example, VS2010 will install C++ Redistributable by default. Thats the reason your application doesnot works in some machine but works in others.
You could try pasting the "msvcr100.dll" in your application bin folder and distribute if you dont want to install VC++ 2010 Redist in all the PC's.
Some of the System.Data.Sqlite.dll modules depend on the "Microsoft Visual C++ 2012 Redistributable Package" .
You can find required dependencies on the official download page : http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
The answers already given didn't solve my problem. I tried to deploy to a VMware server. The solution that did help where given here: http://sqlite.1065341.n5.nabble.com/System-Data-SQLite-Deployment-Mystery-td71752.html Two methods are described there.
When i install this sqlite-netFx45-setup-bundle-x86-2012-1.0.88.0.exe, my app is able to find the right dll.
The second method is to add the dll to de app.exe.config in the debug or release dir. If you edit this file directly, there is a change VC will overwrite the file.
My main problem was that i installed the sqlite package manually. I didn't use NuGet, because i'm behind a proxy. If you do use Nuget, the information in the app.exe.config will be provided automatically.
Using NuGet behind a proxy is described here: NuGet Behind Proxy

My mail-provider has made an update, which generated some problems using Dot.Net Mail in an older Windows Form C# solution. I found, that it is recommended to use MailKit/Mimekit instead of Dot.Net mail. So I decided also to upgrade to newer Visual Studio 2019, where I can use NuGet packages.
I installed Visual Studio 2019, installed MailKit using Manage NuGet Packages (Browse, Right Click, Install) and made a simple test-program in C# (Windows Form Solution) where I send an Email with some attachments.
The solution works 100 % - as long as I execute the solution (both debug and Release builds on the PC where the program is build.
When I copy the Release version (exe-file) to a similar PC (Win 10, DotNet 4.8) I get the following error: Could not load File or Assembly 'Mimekit, Version 2.10.0.0, Culture=neutral, PublicKey Token=bede1c8a46c66814' or one of its dependencies.
The same happens if I transfer the exe-file to a Win 7 - PC.
I have
Checked that both MailKit an MimeKit is listed in the Solutions References
Tried to uninstall and reinstall both MailKit and MimeKit (version 2.10.0)
Tried to upgrade MimeKit to version 2.10.1
It is my first solution in Visual Studio 2019 - as well as my first use of a NuGet Package.
I expected that the built Release Version could be transferred to another PC as a file copy, but something seems to be missing.
I have no clue what to do !?
#Jada_DK, copying executable alone doesn't make the dependencies available on other PC. You'll need to distribute the application through publish wizard or create an installer. Kindly refer the documentation here. Alternatively, if it's a quick sample application you don't intend to distribute, you can copy the entire bin/debug or bin/release folder to another machine and run the application.
I have developed an application using C# (Visual Studio) which runs without issue on my Windows 10 development PC. However, when I copy the application to its intended target PC and run it (Server 2012 R2), I get an exception informing me that a file or assembly could not be loaded: Microsoft.SqlServer.ConnectionInfo, Version=13.100.0.0.
If I copy version 13 of the dll to the program directory of the target PC and run the app, I then get an exception informing me that it cannot find version 14 of the dll. Copying version 14 to the target then give me the original exception, and so on.
I have references to all the required dlls in the application, namely:
Microsoft.SqlServer.ConnectionInfo.dll (the one which is giving me
the issue). Microsoft.SqlServer.Management.Sdk.Sfc.dll
Microsoft.SqlServer.Smo.dll Microsoft.SqlServer.SqlClrProvider.dll
Microsoft.SqlServer.SqlEnum.dll Microsoft.Web.Administration.dll
All are set as: specific version = false.
All of the necessary frameworks are installed on the server. Additionally, the following is also installed on the server, which the program interacts with:
• ColdFusion
• SQL Server 2012 (and 2008 but this instance is not used by the program)
The .exe is installed via an installer and that installation includes the necessary dlls, which are installed in the same directory as the exe.
Full permissions are available on the directory, and the program itself has the highest access level.
The connection string is selectable by the user and defaults to the correct one, depending on where the program is installed.
Does anyone have any ideas which may help me to resolve this conflict?
Thanking everyone in advance.
Regards,
Ken.
ADDITIONAL INFORMATION
The version number of Microsoft.SqlServer.ConnectionInfo.dll shown within Visual Studio is 13.100.0.0. I copied the DLL from the path shown in properties, to the program directory. Guess what? When I ran the program an exception informed me that it could not find version 14.100.0.0!
This is the version of the same DLL as shown on the file's Properties page: 13.0.16106.4.
SMO is always installed in the GAC, so it doesn't matter what files you copy to your /bin folder. GAC'd assemblies override local ones.
You have referenced the SQL 2016 version of SMO. So you must either install that on your target server, or build you project against the version of SMO already present on the target server.
See
https://learn.microsoft.com/en-us/sql/relational-databases/server-management-objects-smo/files-and-version-numbers
Note that because of the hassles with loading and deploying SMO, and SMO's really old API style, it's often better to have your app perform SQL Server administration with just TSQL and System.Data.SqlClient.
[RESOLVED]
Dumbassary was afoot.
I removed all the references from the Visual Studio project, re-added them and it worked.
The issue was caused by a DLL reference which was pointing to the program's installation directory and not to C:\Program Files (x86)\Microsoft SQL Server\130\SDK\Assemblies. As the Properties box was not fully expanded, I failed to notice it.
Hopefully, someone else can benefit from my experience.
Thank you for your comment David.
i created a windows application that uses system.xml and system.io libraries, it reads and writes into a specific file (in same directory).
after i am done, i run the .exe file and its perfectly fine BUT when i tried it on any other computer, it gives an error and doesn't work(doesn't even open).
i think that i should attach some library files such as the xml library ?
I tried publishing as installation file and it also doesn't work
i don't know and don't know how to do that, please help.
System.XML and System.IO are part of the .NET Framework. Check which .NET Framework version your solution is compiled for (in the project settings in Visual Studio). Default for Visual Studio 2015 is the .NET Framework 4.5.2, which is not installed by default on Windows 7! You need to install it for your application to work, but you don't need to copy any DLLs manually.

I just downloaded the 64bit version of the SharpSVN here's the link!
When I run my application, error message displayed. I have searched the net on how to fix this issue but I'm failed. I tried the following solution:
setting the Configuration Manager to x64 as suggested on this post
setting the startup config on this response
also tried downloading x86 and set the config manager to x86.
tried this also, adding assembly link
I'm using Win7, 64bit,.net 4.0.
Solve it.
Change my platform to x86
Output path to "bin\"
Downloaded the x86 of SharpSVN (1.7008.2243.14245)
Add SharpSVN.dll in GAC.
Delete the bin folder and rebuild solution
This is the link for the explanation.
If you're getting this error when trying to access a website hosted in IIS, you may need to adjust the "Enable 32-Bit Applications" setting in your application pool. See this answer: https://stackoverflow.com/a/20525314/12484
This may also come down to a mismatched version of the Microsoft Visual C++ Redistributable Package depending on the version of SharpSvn and the version of Windows/Visual Studio.
Newer versions of SharpSvn have a dependency on the "Microsoft Visual C++ 2010 SP1 Redistributable Package".

I downloaded setup.exe, and then begin to install and it immediately crashes.
On win7 it worked fine. On XP it doesn't work.
Error text:
Unable to install or run the
application. The application requires
that assemble stdole Version
7.0.3300.0 be installed in the Global Assembly Cache (GAC) first.
You'll need to include stdole.dll as a required file in your Publish settings in Visual Studio. Once you publish your app again, it should then include that file in your app when it's installed.
More info can be found here.
This happened to a few people that i had to install a click once application i developed. Basically something happened in their installation of .NET and the needed .DLL's were not moved to the GAC. It's very simple to fix, basically You need to copy stdole.dll from C:\Program Files\Microsoft.NET\Primary Interop Assemblies\ to C:\Windows\Assembly ... that should fix your issue. Including them in the application isn't the best idea, this will fix it for ALL click once applications rather then just that one you are currently building.
P.S. Dragging the files to the location will work, you might get an error if you try to copy it.
