Hmm, not funny ...
Digital signature is not important here.
Before starting tbosdtw.exe, it is important to have a 32-bit environment, because 64-bit does not work.
Is it not clear from the information above?
In my opinion, everything is transparent and simple.
It is depressing that the 32-bit version of tbosdtw.exe does not work without first profiling the environment.
It is of course an obvious error.
I apologize for the unpleasant opinion. But I got the impression that no one is testing the code on a real 32 and 64 bit OS from NT4 to 10.
I must note that your programs are very high quality and beautiful, but these simple mistakes are strange against this general background. They should not be.
I apologize for being perhaps too rude. But, in my opinion, otherwise it will be difficult to wake you up.
Update. Corrected the script above ..
