Digital Signature with relative certificate path not working

[oleg-shilo]

You managed to solve it because you switched to an absolute path. Your process's current directory has no impact on absolute paths. Life is good. :)

However when you were using relative paths then they are always relative to the process current dir.

absolute_path = curr_dir + relative_path

When you set SourceBaseDir you are saying to to WixSharp compiler "during the build, do not use currentdir but SourceBaseDir for all MSI input files relative paths"

absolute_path = SourceBaseDir + relative_path

This will be happening during the execution of WiX compilers (project.BuildMsi() call) but not when you are calling your Path.GetFullPath(...)

I think the problem is caused by the SourceBaseDir being set to some location.
All relative paths are resolved against project.SourceBasedDir, which by default is a currentdir of the current process.

Thus you will need to find a way to adjust your relative path against your Constants.SOURCEDIR

Hi @oleg-shilo
But Path.GetFullPath resolves to absolute path already (which is also proved working if I give whole absolute path in pfxPath.
So it is confusing me.

1. Do you mean to say Path.GetFullPath gets resolved relative to SourceDir when MSI is being run?
2. If yes to 1, is there a way I can use a public property for certificate path & set property at some event so that MSI can resolve digital signature?

Hi @oleg-shilo
I somehow resolved it by doing below steps, but I am still unclear about concept of relative path being used in WixSharp.

1. I pasted licence.rtf & certificate file on the path where MSI gets generated.
2. In the script, I took Path.GetFullPath of those files, like, Path.GetFullPath("licence.rtf") & Path.GetFullPath("certificate.p12") in respective variables licencePath & certificatePath.
3. I used these variables in project.LicenceFile & DigitalSigntaure respectively.
4. MSI got compiled and it got signed as well.

Please refer below screen shot for code changes.

Please refer below screen shot where I pasted files

Question : Can you please explain this concept of relative path as I am still confused why and how it worked?
