Hello sir i understand, what you write , but i don't have the source code of the application and cannot modify it.
is anything can be fixed with otvdm ?
I tried with version 2023 you released yesterday, but still problems after buildbcd

Yes, the patch I made fixes the problem with buildcommdcb but there's another issue that unfortunately is not clear from the trace. Since I don't have the program to test directly, I couldn't have known that that didn't fix it fully.

Ok how is it possible to send it directly to you, i don't want to post it on internet ?
thank you
