Common PS1 Opening Problems

Microsoft Windows PowerShell Not Present

If you attempt to load your PS1 file, you experience a message such as "Can't Open PS1 Files". Generally, this is experienced in %%os%% because Microsoft Windows PowerShell isn't installed on your PC. You won't be able to double-click to open your PS1 because your OS doesn't know what to do with it.


Tip: Another PS1-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Outdated Microsoft Windows PowerShell

Occasionally, you might have an outdated version of Microsoft Windows PowerShell installed that's incompatible with your Windows PowerShell Shell Script type. Download the latest Microsoft Windows PowerShell version from the Microsoft Corporation website to ensure you have the correct one installed. This problem is predominately due to having a Windows PowerShell Shell Script file version that was created by a newer version of Microsoft Windows PowerShell than what you have installed on your PC.


Tip: If you right-click on your PS1 file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Ultimately, most of the difficulties opening PS1 files are due to having the wrong version of Microsoft Windows PowerShell installed.


Other PS1 File Opening Causes

Assuming you have the right Microsoft Windows PowerShell version installed, other problems can prevent you from opening PS1 files. If you're still experiencing problems opening PS1 files, there could be other computer problems. Additional factors include:

  • Corrupt Windows Registry file path references for PS1
  • Corruption of the PS1 file description inside the Registry
  • Invalid installation of a PS1-associated program (eg. Microsoft Windows PowerShell)
  • File corruption affecting your PS1 file
  • PS1 file integrity has been compromised by malware
  • PS1-related hardware has device drivers that obsolete
  • Insufficient system resources to successfully open Windows PowerShell Shell Script files
