How do I uninstall this stuff?

I used xampp to install apache / php and wordpress on my pc but once it was all installed and set up I could no longer use windows mail or firefox – firefox thinks it’s already running (it isn’t) and mail tells me there’s a dll missing and that it is also running.

I tried rebooting with no success.

So I decided to remove the apache, php and wordpress but they don’t show in windows control panel / remove programs.

I did manage to uninstall the xampp but can’t find out how to remove the rest. I tried contacting apache but it’s pointless, they don’t want to help anyone. Ditto for php.

I still can’t use my windows mail or firefox.

I’m on vista home premium if that’s any use.

Any ideas?

Thanks
