I tried version 0.0.7.6 in 10 x64 PE and in 8 x64 PE and in 8 x86 PE and in 10 x64 OS but without succes
The Hive Selection Window appears, but the OK button does not work .... and a log file is NOT made ....
Now the Cancel and Close X button work and Exit the program, so that is an improvement ....
If you have PE in mind for your app, then it should certainly be 64-bits whereas now it is 32-bits
The most compatible PE for BIOS + UEFI is Win8.1SE x64, which has limited 32-bit support.
The 8 or 10 x64 PE of Microsoft have no 32-bits and no GUI support at all
