I tried to install Acrobat Reader but it gave me an error message saying "Corrupted Checksum" or "Invalid Checksum", something like that. From that point the way I used to log in to computer changed automatically. I used the xp welcome screen to allow users to click on their usernames to log in, but it changed to the conventional login interface in which each user has to type his/her username to login. Moreover, the the colour of background when login form appears is black when it should have been blue by default.
As a solution to this problem, I tried to delete all the keys related to Acrobat Reader but regedit did not run (although I am the system administrator of my PC). Then I tried to restore my PC to an earlier date. System restore didn't open as well.
As the last try, I formatted my C drive and reinstalled windows xp. It worked fine. But again I tried to install Acrobat Reader and it gave the same checksum error and everything that I've mentioned above repeated. However, I reformatted harddrive once more and tried to install Acrobat Reader again and then again I faced the same problem. Now I am not going to do anything prior to having some knowledge about what's actually going on in my PC.
I don't know what to do now. Someone please help.
Thanks.

Did you redownload Acrobat Reader between install or did you reinstall from the same file each time?
Do you have up to date antispyware/antivirus software installed?

well, go to filehippo.com, download the adobe acrobat reader (latest version your computer can handle) and then SAVE IT TO SOMEWHERE ELSE (like a flash drive, not on your harddrive)
Then run the program directly from the new location. Does it work now?

Forget about that behemoth, Adobe Reader. Get FoxIt: http://filehippo.com/download_foxit/. It's much smaller, faster, and does very same thing.

or another other pdf reader. There are other ones too that read pdf files just ok.

Sounds like a case of "if it hurts, don't do it".
But seriously, if it gives you a checksum error there must be something wrong with the
installer. probably screwed up and changed the associated of executables.

go to filehippo.com and download the file. I have been doing that for a long time and no problem so far. It is always updated with latest versions of the software(s) that many people use as well as all previous versions if you like to use older versions.
