Software won't install on 1 Win 7 64 bit but will on another - help!

I have an Acer Aspire R3700 home theater PC running Win 7 Home Premium 64 bit. I also have an Asus 1215N Notebook running Win 7 Home Premium 64 bit. Several pieces of software (including Adobe Photoshop Elements 2.0) WILL install and run on the Acer but WON'T on the Asus notebook.
What is missing or different about the Asus that is preventing it from installing this software?

This might help you understand.

What Adobe programs and versions are compatible with Windows 7? - Microsoft Community

I think you misunderstood the question. That site says APE 2.0 WON'T run on Win 7 period. As I stated, it will run on one Win 7 64 bit PC but not on another.

What I was trying to say was that according to Adobe and Microsoft it should not run on either system. Some how you got lucky on one computer.
System requirements | Photoshop

If your hardware is capable you could try copying the program to a thumb drive off of the working system and removing APE from the non working system. Then installing APE from the thumb drive to the now clean computer (no APE). It might take what ever setting from the working system to the other computer when copied. That is a long stretch. I would disable your anti virus and firewall during this transfer.
Make sure when done you enable your anti virus and firewall again.
As a general rule it is not good to try and force a non compatible program on a Windows 7 computer. It will probably cause other problems.

I have an Asus N53SV running windows 7 64bit and installed Photoshop 2 and runs perfectly... Must be a hardware issue not a windows one.
