In Win XP I used a simple batch file to copy GhostScript dll to Windows\System32 with a batch file from the Installation CD. With Vista that all seems to be prevented and requires permissions to run. I have no preference of batch, VBS or Net except I am vauge with all. I would like the could that would work like the old XP copy the files, a Vista message to OK would be acceptable.
copy gsdll32.dll %windir%\system32\
