An error has occurred during web site deployment in App Service Editor

I made some changes in the QnAMakerBasDialog.cs file, in trying to edit the default threshold. I did not change any other thing. When I tried deploying my changes at first, I was not getting the expected response and so I went back the editor to reverse my changes. It was at this point I started getting this error message.
I need help in reversing all changes if possible but most expecially in getting "test web chart" and all my channels working again.
Please see error message error:
kindly note that I tried this in the kudu console but still got the same error message

Surprisingly, I also encountered this problem. I also encountered this problem in Buid after modifying the Azure Bot code!
Even with this error, my build is successful

How can I enroll certificate while no user logged in?

I use this link to Enrol new Certificate.
When the Windows is lock or logged in everything works fine and create request and install it properly.
Running the code as Windows Service, so when I restart the machine, and service is starting cannot create request and get the error the following line:
objPrivateKey.Create();
And the error is:
System.IO.FileNotFoundException: CertEnroll::CX509PrivateKey::Create: The system cannot find the file specified. 0x80070002 (WIN32: 2 ERROR_FILE_NOT_FOUND)
at CERTENROLLLib.IX509PrivateKey2.Create()
Any idea how can I fix this issue? Thanks

Access Denied when running Windows Service

I have created a Windows Service using ASP.Net Core 3.x and C#. I started with the new Windows Service template when I built the project. When I run it from my development environment or from a console window it runs fine. When I install it as a Windows Service and attempt to start the service I get an
"Error 5: Access is denied." error.
I tried numerous things which I will outline below to eliminate the error but nothing seemed to work so I downloaded the sample app provided by Microsoft, at sample
Same result...when I run the sample app from within Visual Studio it runs fine, when running as a service I get the Access Denied error.
I am running all of this on my local machine, which I am an admin on.
I originally tried to run it using the default Local System account; got the Access Denied error.
I changed the Log On As to my domain account, the same one I use to log into my local machine which is an admin on this machine; got the same Access Denied error.
My account has the privilege set to run as a service.
The Event Viewer just shows the one message which says "Access Denied", no other messages are created.
I believe the Access Denied error is occurring before the C# code is even executed. What makes me believe this is that I added one line to the very top of the Program.Main.... File.WriteAllText("C:\\temp\\ws.log", $"Test of Worker Service # {DateTime.Now}. Content Root Path: {AppContext.BaseDirectory}");. My account has full access to the temp folder. This file gets created when I run the app from Visual Studio but it does not get created when I run the app as a service.
I have read numerous web sites, include this one and this one. No luck, everything I tried from these sites still produce the Access Denied error.
I have run out of ideas and am hoping someone here can provide me the answer. Thanks!

I found the solution and believe me I feel really stupid!!!
When I installed it as a service I only put the path in "binPath".
sc create WindowsService1 binPath="C:\temp".
Once I actually added the executable to the binPath parameter everything worked.
Changed it to sc create WindowsService1 binPath="C:\temp\WindowsService.exe" and it worked.
I know it is an Id10t error but Microsoft should really provide better messaging for the "sc" command. A message like "Cannot find file specified in the binPath parameter" would have been really helpful. Would have saved me about 6 hours of work.
Thanks everyone for reviewing and replying to this question.

Windows Service - UnauthorizedAccessException Error when Installing Service (C#)

So I am trying to create a service using C# in Visual Studio 2017 and I keep getting an error when I try to install it.
Right now, I don't even have anything in my service, I just want to be able to install the service. I created a new Project in Visual Studio 2017 using the Windows Service (.NET Framework) template under Visual C# > Windows Desktop. I then added the installer via Right Click > Add Installer. For serviceProcessInstaller1, I set the account to LocalSystem. And...that's it!
Now, I try to install it. I open up command prompt (run as administrator) and I do
InstallUtil ServiceTest.exe
Things start off smoothly, but then I get a message:
"An exception occured during the Install phase.
System.UnauthorizedAccessException: Attempted to perform an
unauthorized operation."
What could be generating this message?
I've googled and tried the following things:
Ensure I run command prompt as administrator.
Assign Full Control to
the project folder to my admin account.
Configure permissions to Full
Control for admin account in the security log of regedit.
Log into my
computer as an administrator (rather than regular user) and run it
that way.
Despite these things, I keep getting the same error. What else could I be doing wrong? Would really appreciate some advice!
Note: I am trying to install this service locally on my computer.
Edit: Per request, here are the logs. I named my project "FailedService", by the way, since I can't get it to work!

Restoring event log to previous state for source Service1.

I was FINALLY able to resolve this issue. I was able to get to the bottom of it by using SysInternal's Process Monitor. I opened up the program and had it take logs for InstallUtil.exe. From there, I began to search for any logs that said "Access Denied". As I sorted through them, I noticed something interesting: it was trying to create a registry key, but it kept failing!
So I went into the registry and created a key named "ServiceTest". After that, I ran the InstallUtil command again, and it worked!
If anyone else is having trouble, the solution is to create a key named after your process name in the following location:
HKLM\System\CurrentControlSet\Services\EventLog\Application\

Enter the full path to installUtil & your service binary in an elevated prompt, that could do.

error of updating an C# web service application by accessing a URL from MS installer command "msiexec" in C# VS 2010

This question is related to my previous question.
I need to publish a C# application (that has been set up in IIS 6.0 and built in VS2010) to a desktop with win7.
I have set up IIS on my desktop well. Now I can install the application on my laptop by accessing the URL
http://myDesktopName.domain.com/MyApp
pointing to a physical location in desktop
e:\myPath\myApp\myAppService.svc
When I publish a new version of the web service, the application should get updated when I open it.
But, it gave me an error:
**the filename,directory name, or volume label syntax is incorrect**
After searching online, I found this error is normally caused by some unacccepted chars in the link. Here is the code that the msi (MS installer) needs to access and get the new version of the application.
System.Diagnostics.Process.Start("msiexec", "/favmuso \"" + myurl + "\"");
here,
myurl is http://myDesktopName.domain.com/MyApp/MyAppSetup.msi
Here, http://myDesktopName/MyApp/ is the virtual directory set in IIS 6.0 on my desktop. I can access and download it from IE in my laptop without any problems.
But, when the application notified me that a new version is available for updating the old one, I clicked the pop-up ballon on the application icon and then I got the error:
Error 123. The filename, directory name, or volume label syntax is incorrect.
If I try to access it from the C# code, I got the same error.
Then, I did a test by running
msiexec **/favmuso** http://myDesktopName.domain.com/MyApp/MyAppSetup.msi /Lv mapp_msi.log
In the log file, i found :
MSI (s) (80:DC) [18:04:33:089]: SECREPAIR: Failed to open the
file:http://myDesktopName.domain.com/mypath/\myAppSdetup (10).msi for computing its hash. Error:123
Error 123. The filename, directory name, or volume label syntax is incorrect.
Why my applcation setup file name was changed to
\myAppSdetup (10).msi
The "/favmuso" options can be found at
https://technet.microsoft.com/en-gb/library/cc759262%28v=ws.10%29.aspx#BKMK_Install
Any help would be appreciated.
thanks

So I noticed that you've asked this question elsewhere, and everyone was focused on the /favmuso piece of it.
I've been recently exeriencing this issue when trying to repair MSIs with a URL source when the original application was installed by SCCM 2012.
The workaround I found was to add a registry value at HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer. The value below causes the MSI to skip the problematic portion of the repair and move on.
Name: SecureRepairPolicy
Type: REG_DWORD
Value: 1
To be a bit safer, you look into setting the registry value to 2 and using a whitelist as described in this Microsoft article: https://support.microsoft.com/en-us/kb/2918614. (Ctrl+F "Steps to opt-out the affected programs".)
