Thx Steve_U, i also put it under the hot list.

But… all the things you posted didnt had any effect on starting BMS with the Anniversary update from Windos 10.

It appears out of the log file that it didnt start op the ntdll.dll file out of the SysWOW64, only from the Win32 file, which seems that it causes the problem to start up BMS in 64bit.

For now the only medicine was to go back to before the update, after that it worked, BUT before you do, save all your config files, and campaigns etc, because it seems the register file was corrupt…

For now it works, i truly hope there will be a better solution for this in the future…

But thanks again mate!
