When I reboot to complete the installation of Daemon-Tools 3.26, I get this error:

C:/Windows/Installer/20E702BA-68AE-4F86-8446-CBDE99184748

It says that it already exists and needs to be renamed or deleted. Unfortunatly for me that file doesn't seem to be on my computer, neither does the Installer folder which is specified above in Windows. I tried installing an older version but it gives me an error also. Any help?

I'm running XP Pro on an AMD
