2010 installation problems on XP re: DLL / integrity / debugger

Hi everyone,

 

I'm trying to install NIS 2010 on my XP desktop computer but before I can get anywhere I am immediately told there is a problem to do with one or more of the following:

 

DLL loading program

debugger detected

integrity violated

 

I've browsed through the forums and can't find any relevant info. The only time I've seen this come up is in relation to the 360 version. If someone could explain how I can fix this I would be greatly appreciative.

 

If it makes any difference, I've followed installation instructions up this point; uninstalling other security software and clearing out temp / cookie folders.

 

Thanks,

 

Sam
