Great, good news Finally you managed to do it without the MS detours package and the tiny $10000 license fee
I would personally attached runscanner2.0.0.0.7z, it is light enough, to avoid downloaded at build time,but Versions.ini to get your latest version is well too.
However, I wonder if it would not be good to have both 32/64 bits versions available in x64 PE !?
Think its a file permission problem with win8.1 pe se. I could not get the file version of ntdll.dll even with explorer. If I switch to win 10 pe se then it works fine.
But cause you mention Windows 10, could it be that the new system compression is set on these files.If so than the WofADK driver is missing.I think we should add it to the older SE projects.
