Hi Jonnyboy, After several tests, I understood that there was no problem between v0.517 and f.f 3.06. The problem was because of my system. You're right! :thumbsup_anim: However after creating f.f 3.06 with v0.517, I tested f.f I saw that there was an unneeded folder in C:\Documents and Settings... and the folder name is "$Admin$". If you are interested, i can send you log file and folder name in details. PS: I used nLite, and I created another administrator account (named "admin") in $OEM$ folder. Can this have anything to the with the subject? Thank you so much.
