Hello Mike,
Did you download compliation 2 DVD for the 7.30 GUI?
If yes,download the lastest sapsetup patch 34 from the note
http://service.sap.com/sap/support/notes/1587566
,run nwsapsetupadmin.exe,click on 'patch server' and point it to the location of the downloaded
patch.
Then click on 'Check Server' to ensure there are no corrupted files on your installation server.
Try runing the install again and if there are errors,check the sapsetup.log files and advise if
any errors by searching the text file for 1E or 2E in the logs.
Paste them to the reply if neccessary.
Regards,
Jude
