Hi Bumpyknuckles, I also had problems with an older program which had pdf Help files and which was looking for the Acroread.exe file as used in Acrobat Reader 4.0. Consequently, it wouldn't work with Acrobat 5.0
Acrobat Reader 5.0 uses the file AcroRD32.exe so I copied this file into a spare folder, renamed it "Acroread.exe" and then copied it back into Acrobat 5.0 so that I now have both the AcroRD32.exe and the Acroread.exe files in the same Acrobat program. All pdf programs now work with the Acrobat Reader 5.0. Maybe you do something similar with version 6.0?
