Activation error, resolution issue

Today I send a post to help out people that might have experienced a problem with registration, on Windows XP, where not all software were valided at the step of Service center because of Internal error. The thing is that you have to get installed your software package on the directory C:
(- not on any other letter, suppose G: - ). If you have an other letter as main directory you can look at these instructions from microsoft website to change it :

For me it was not enough, because I could not change the letter. Consequently I had to create a new ntfs partition that I could easily name C: from the menu provided with the link above. And then install again the whole package in this place. When finished it worked fine.

Good luck.
