I get the same problem, it is not driver issue, it is complaining about the drive when trying to locate the certificates under Cert:\

Here goes the verbose log:

For what I understand the problem is with dir Cert:CurrentUser\Root, this is only a valid command in powershell, if you run that in a cmd you will get the same error. That's why powershell tells you to avoid aliases, maybe if you use Get-ChildItem instead it will work?

[caiohamamura]

I think I get it, it is because I've installed the Powershell Core v7. So that may have messed up with the original PSModulePath that the regular Powershell also uses. If I change powershell.exe to pwsh.exe and add a -Command argument before the actual command in: https://github.com/YehudaKremer/msix/blob/ab1d4b24dba477265fec2f0a48ee4c00b3d316b5/lib/src/sign_tool.dart#L151

Everything works! I don't know how to provide a solution to that issue tough, since it is not everybody who has the pwsh.exe installed.

[caiohamamura]

Okay, now I kind of get it. The only way to reproduce this problem is to run the command from inside the pwsh.exe itself, then it will mix up what Modules to load because the pwsh.exe will inject its modules directories inside $env:PSModulePath, so when we call powershell.exe from inside, it will try to load the Powershell Core modules and the problem will arise.

A way to hack around it would be to reread the $env:PSModulePath from the registry before running the dir Cert:\.

We could replace the: https://github.com/YehudaKremer/msix/blob/ab1d4b24dba477265fec2f0a48ee4c00b3d316b5/lib/src/sign_tool.dart#L154

With:

      "\$env:PSModulePath = [Environment]::GetEnvironmentVariable('PSModulePath', 'Machine');dir Cert:\\CurrentUser\\Root | Where-Object { \$_.Subject -eq  '${_config.publisher}'}"
