Strange thing. An old copy I found on a back up disc worked. The new download still would not install even when I changed the .txt bit.
set up asks for
File9=1,,Readme.tx_,Readme.txt,$(AppPath),,,3/10/2001 12:23:24,10644,,"","",""
No idea what it means.
Got the old copy to work in the end, thanks for the help.
