Set the TEMP = to a location that all users have Read/Write/Create to like c:\Temp, this is where Phrogram will compile programs and has to be on the local PC when you change the location of the files.
Oh by the way the folder for your Examples and Media must start at My Phrogram Files\ ...... so I:\My Phrgroam Files\... is what you want.
If you still have issues set the MediaSearchPath = I:\MyPhrogramFiles\Media Files
If you still need help contact Support@Phrogram.com
