I downloaded WinBuilder (082) and main scripts (updates.boot-land.net and w7pese.cwcodecs.net). In source menu I pointed folder where is Windows 7 x86+x64 sp1. Also, copied some drivers to the requested folder. Seems everything well, okay. I pressed play button and the program started its work. While it's processing scripts, I found out that program is stuck on "1 - copy files [1-files.script]" and message "please wait: unmounting wim files". Then I got information window: build stop due to an error. I tried building custom windows 3-4 times and getting this error again and again. I don't know how to solve it. Winbuilder's path is C:/Winbuilder/winbuilder_2015.03.07 and my win7 files on desktop.
Here are some logs:
Please help me, I'll be very thankful to you
P.S Sorry for my bad English...
