Please use this test build
. It will only produce a single DEBUG entry to the installation log (you can save it).
PS. The only thing that would help me to reproduce the issue is to have exactly the same Windows as you do.
And the only way to achieve it is to create a copy of your Windows drive using Disk2vhd utility
. The disk image will contain your personal data, so please clean it by mounting the resulting .vhd file
and removing all your data. Also I'd need a story how to reproduce the issue on this machine.
Yes it really sounds crazy
