I did a disk clean-up and I tried to remove some applications that I didn't use anymore. So I went in there but got confused (didn't think I was confused) and thought that if i ticked an application it would delete. But oh no! Clicking it keeps it so I unticked all the others and now I have lost many many applications. I have tried to re-install the applications through the disk cleanup by ticking them but then it says "Please insert the Compact Disk labeled 'Windows XP Professional Service Pack 2 CD' into your CD-ROM drive (E
and then click OK." I have "Windows XP Professional Version 2002 Service Pack 2". I have tried a file from Microsoft but I don't know what I am doping and I double clicked the .exe application and it said "... is not a valid Win32 application." I was wondering if there was any way I could get all these applications back as I don't have the CD. I was thinking maybe an .iso image? Please help anyone!
Thanks so much if you can help.
