Failing to open mstsc on Windows Xp

[slayer69]

I installed my windows xp OS using Nlite which I aquired here at MSFN. I tried using MSTCS and it gave me an error saying "Windows cannot access the specified devise, path or file. You may not have to appropriate permissions to access the item. I've also tried to reinstall it, but I get ' Remote desktop connection cannot be installed cause your operating system already has a built in version. I am logged in as te administrator of this machine I trying to run it from.

Any help would be appreciated!
