with Reg2Inf i converted my reg to inf .. and made cab file which i integrated as hotfix in nlite. but soon after that my setup stopped when its was loadin hivedef.in and told me line 643 is corrupted and setup can not continue press f3 to restart... so i deleted and line 643.. and started setup again. again same error but this time line 644.. so i decided to delete similar entires, there were about 5 after that setup went fine but at t13 it gave me Advanced INF Install Error.. and when finally desktop was loaded.. but somehow it broke ie7 installation and didnt apply any of the nlite tweaks.
