Are you suggesting there is something to be gained by getting another copy of the same thing?
XAMPP does not need to be 'installed' it will run in its own environment... and doesn't need any path or registry entries... it is in fact 'portable'. The installer is a convenience that adds menu links and will put an entry into the enviornmentals and registry... when we set up a ZedFiles package for distribution http://www.zedfiles.com it is 'copied' to the host computer...not installed and we just include a shortcut that can be put on the quick launch or whatever...
So, I was suggesting that you download an archive or zipped version...the 'Self-extracting ZIP archive Economical: XAMPP as very small self-extracting 7-ZIP archive' is the easiest and simply extract it to your desktop... leave it there for now and open it up and run the setup.bat.... try the controller in non service setting, start Apache and MySql and see what happens... (remembering that you can not have any services from previous installs running...see list and do that drill).
Depending on what you have running... you may have to alternative port Apache and MySQL... you should run a port check too. If that is the case, go to the DTX section of the ZedFiles site and there is a alternative controller there along with instructions in the readme.
We build and distribute portable xampp test beds all the time... every once and a while there is an XP system with its own personality... hey, you may be one of the lucky ones
