Every time I run a .dll injector I get the Windows error "Windows cannot access the specified device, path, or file. You may not have the appropriate permission to access the item".

Really frustrating. I have used Google to the best of my abilities to find an answer as to what is wrong, but I can't find anything to help. I have tried a few random injectors along with PerX and Jhem's injector. I have disabled my antivirus and firewall and still get the error. I am using the administrator account and selecting "Run As Administrator" just in case. I am using Windows 7 Home Premium 64-bit if that is of any concern.

Any and all help will be greatly appreciated.
