Windows - Installation scripts not successfully executing

I am having an issue with googet on a single server where it is not executing the installation script defined in the pkgspec file. As far as I can tell, it's not successfully calling powershell. If the install script is executed manually, it runs successfully.

I can repeat the issue with the following command (installation package does not matter, experience is the same regardless of package):

`googet.exe -verbose -root c:\temp\jcl\Googet install -sources https://packages.cloud.google.com/yuck/repos/google-compute-engine-stable google-osconfig-agent `

It will extract and copy all of the files and then log:

```
INFO : 2021/06/29 15:37:12.722922 system_windows.go:76: Running install command: "packaging/googet/install.ps1"
ERROR: 2021/06/29 15:37:12.729706 googet_install.go:165: Error installing google-osconfig-agent.x86_64.20210607.00.0+win@1: open NUL: The system cannot find the file specified.
```
Again, powershell works by hand, the installation script is in the cache folder where it was extracted.

I pulled down the latest googet sources and liberally sprinkled some logging statements around the install.go and goolib.go files to see if paths, filenames, etc were being passed successfully. Here's a truncated excerpt from logging statements output from a modified googet version:

```

```

**I strongly suspect that the issue is within the OS and/or its configuration** but it only appears that googet and other google services installed on the OS are impacted by this (e.g., OSConfig Agent service is not able to run powershell to determine installed updates). It appears to successfully hand execution to [os/exec func Run](https://golang.org/pkg/os/exec/#Cmd.Run) which then generates the error. I am somewhat at a loss as to how to troubleshoot this further. Any direction you can give would be greatly appreciated.
