I have several, and they all are a little bit different. There is, however, a common factor; which is you thinking it's a good idea to keep installing loaders when you have one that works. It's that or you're a troll and/or an idiot.
I already told you, go reinstall Win 7. All this time you been posting you could have already reinstalled Windows. And don't open more threads on the SAME subject.
I don't believe this guy. The five page thread he already has was sufficient enough and full of enough resources for him to solve his problem. First he had an HP slic, then it was DELL, then he had to change his certs. He's like the energizer bunny of "I can't figure anything out on my own."
If you look at his first post in his first thread he said he was using 'windows 7 toolkit 1.8 to activate' so he has got a 'Franken build' with messed up tokens.dat and other files. Thats why the key won't work. The best answer has been suggested many times. REFORMAT & REINSTALL.
ADD to this, "REFORMAT & REINSTALL", activate correctly. avoid the loaders and RC token changers. This is where ignorance is not bliss... But with all the info given, we are leaving ignorance and coming up on stupidity..
