Of these apps only Nero and Winrar actually install. Diskeeper - an error message saying it can't find setup.exe . When I check the folder, it is indeed not there: instead there is a corrupted file $temp$.~~~ . The file on the XP CD is fine and runs properly. I don't understand why the corruption. It's as if it stopped copying the file in the middle.
For Acrobat, Flashget and WinISO - there is no error message. They simply don't install, even though they are properly copied to the HD. The switches I use are from this board and the main page.
Any ideas?
Thanks.

this works for me

another mistake:should be:and the following:should be:

Thank you both guys, for the debugging ! That's why I never went into programming ....
Any thoughts about what's going on with diskeeper?

use the switches /S /qb for diskeeper. Watch that Capital S

Thanks eagle.
actually the /s /v/qn switches work better than /S /qb because I don't need to click the Next button. My problem is: why does the setup.exe file get corrupted during the copying to the disk?

As for Winiso - I still need to click Next buttons. Any way arround this?
edit - I just used the /s on it and it worked fine.
