Cannot open Reader program, no error messages (Windows XP, SP3)

Question

Hello all! I am hoping someone can provide a solution to my frustration....
Earlier this summer I was having some computer trouble. The computer was under warranty - HP came out and changed the memory and system board.
I have not been having any issues except for ONE thing - I cannot open Adobe Reader to view PDF files. Any PDF files on my system show the Adobe icon, but when clicking on a PDF file or the application itself, nothing happens. The hourly glass shows up briefly and then goes away, but otherwise, nothing.
Temporarily, I got by using another PDF reader. Unfortunately, some of our business systems only work with Adobe, so getting Adobe to work is now critical.
What I have tried (with no luck):
1) Uninstalled Reader, did a system search to remove all Reader files, re-installed latest version
2) Searched the Adobe community and other internet sites for help - tried a Microsoft fix, Adobe cleaner program, went into the Program Files menu to accept the user agreement, etc.
3) Installed earlier verions (9.5, and then 7.0)
Any other ideas? I called back HP, and they tried to be helpful but said it was a software issues since all other programs were running successfully. They suggested I re-install the operating system!
Thank you for your help.

I would recommend adding 4 GB more, you need at least 4GB-6GB for R12 only (not including the OS).
Please see if (RW-50004 Installing EBS 12.1.1 Failed At 53 % During OH Registration (Doc ID 1592143.1)) helps.
