Unsigned Powershell scripts from HTA

I have created the below batch file and it works flawlessly as long as I run it manually.

However, if I run the .bat file from a HTA application, PowerShell says that he can't run the script because it is not signed/not trusted: "File cannot be loaded because the execution of scripts is disabled on this system".

Is there any fix/workaround for this without having to actually sign the script?

Batch file:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noexit -command ". '%cd%\temp_oooscript\wrapper.ps1'"

Thank you.

Solution

  • YES!! Found the bloody solution!! the HTA file needs to be run from through the mshta.exe from system32 instead of SysWOW64. Woohoo!!!
