Can't upgrade to 3.5.x, or uninstall (RC)

I have the following problem with a Dell Optiplex, running Windows XP: I can’t uninstall the RC version of LibreOffice, nor I can’t upgrade to the current version of it. I’ve even tried REVO Uninstaller, installing from Comand Prompt (using administrator privileges) and everything seems to be useless: All I receive is a “Internal error 2330, 23” , message, mentioning a folder within the LibreOffice main folder in C (presets folder)

Funny thing is, when I try to open the folder referred in the error message, this is why I got in answer:

“Disk in C is not formatted, would you like to format now?”
