Cannot create file "c:\prbaddata.txt". Access is denied

We have a Citrix environment where the local drive for each user is H:\ Drive. When opening projects users sometimes experience the error below. This error is hard coded in Primavera so the location for the file creation cannot be changed. Does anyone know under what conditions the application tries to create the C:\prbaddata.txt file and what information would be captured in the file?

Application Exception:
Type: EFCreateError
Event Code: CCF"A-1288-1
Description: Cannot create file "c:\prbaddata.txt". Access is denied
