"Error while updating pvaultupdater" message received when launching pVault via terminal server or published remote app

Issue

The error message, error while updating pvaultupdater, generated when launching pVault on a terminal server or from a published remote app.

This is typically due to the %temp% environmental variable on the terminal server being set to a path that does not exist. This is often caused by an overly aggressive task scheduler routine that deletes folders in the traditional Windows Temp folder location.

Resolution

1. Log in directly to the terminal server as the affected user(s).

2. Open a File Explorer window.

3. Specify the path: %temp%
   
   You should receive an error with text similar to the following:
   
   Windows can't find 'C:\Users\Ron\AppData\Local\Temp\4'. Check the spelling and try again.
   

4. Create the specified folder so that the %temp% path is resolvable.

5. Repeat for each affected user.
   
   As a proactive preventative measure, the terminal server administrator should closely scrutinize their Windows Task Scheduler and GPO, and verify no tasks are set to automatically delete any Temp subfolders.
