Check in task manager and check for firefox.exe in task manager. Or install firefox by changing the destination folder.

The program must close to allow a previous installation attempt to complete

Check and tell if its working.

mha007; I tried the method you pointed me to. The result was no files named xpicleanup.dat. So I am still stumped. Is there anything else I can try?

Case in point why I despise windows standard add/remove as it leaves files & registry settings behind. I use a program called REVO Uninstaller which basically is a third party uninstaller. How it works is it runs your standard built in uninstaller then once that is completed it will scan your PC for leftover files & registry settings. You would be amazed at how much is left behind that windows said it supposedly took off. The link to REVO is below, give it a try & I am fairly certain it will solve your problem/issue.

firefox.exe won't show under applications from the task manager, rather it shows under processes tab from the task manager, from which it must be selected and end process selected.

I did it! Just as you said, I created a new folder and downloaded FF6 into it. It loaded, picked up my preferences, and launched with no problem. Thanks for the help. And for teaching me a new trick.
