As you suggested me, I installed v4 because I had a out of memory on 3.7.
On windows 10 1803 with 16GB of RAM and 108GB free on C drive. Configured the application to import data from mame64 v0.198b stable (romCenter and mame installed in C:\Program Files, not C:\Program Files x86). The destination file is configured to be on the D drive who have 643GB free.
I have receive the following message right at the begining of the creation "Unable to extract datas from emulator c:\program files\mame\make64.exe".
Tried to find any logs in the event viewer of the program folder or appdata, can't find any.
