BuildMsi() Requires elevated privileges

[Amit-ram1103]

I'm using the BuildMsi() method of WixSharp.Compiler in my Web Application. I have hosted it in IIS and when I run the Application Pool in Local System account (Highest Privilege), the method creates a msi file and returns the path of the file. Whenever I run it un ApplicationPoolIdentity, msi file isn't created and null is returned.

Need help in overcoming this issue.

Hello
Did you try to run as admin directly? Do you have some log?

[Amitram1103]

I didn't try to run as admin directly.
Once I upgraded to wix5 and installed the necessary Nuget packages, the BuildMsi() is returning null instead of created a msi file and returning the path.
Then I tried to run it with elevated privileges and it was creating a msi file as well as returning the path of the file.

This means that when your build script (setup.cs) fails it prints the error messages in the build output some dotnet.exe/msbuild.exe can interpret the errors and fail the entire build.

If you want to detect the failure in the build script itself then you need to check the return value of BuildMsi as you did.

It is returning null always. And when I check the folder, the msi file is not created.

It cannot be always since you wrote this "Then I tried to run it with elevated privileges and it was creating a msi file as well as returning the path of the file."

So for some reason in that environment, you need to be elevated.
I advise you to check the build output and look for the error entries. If this does not help, share your project so I can try and see what is happening.

You can also debug the project by yourself. Just disable 'just my code', put breakpoint at BuildMsi and go in with F11 when the breakpoint fires.
