Did you really mean FTN77 or should it be FTN95?

Either way, I would need to be able to step through the code and that is not going to be possible for versions dating back to 2010 and befo ...

At the moment I don't know what the ...

As a standard practice path names are restricted to 260 characters but I can't see anything in the source code for Put_DIB_Block@ that would cause a problem.

If you can send me a short pro ...

1) Is it 32 bits or 64 bits?
2) Do you know what is calling CCOPY#?
3) Which version of FTN95 and the Silverfrost DLLs are being used?

If you have C++ code that compiles with 32 bit SCC but not with 64 bit SCC then it is worth reporting this by sending us sample code that fails.

64 bit SCC is not fully supported but it is ...

If you can manage without debug options and you don't need the iostream functions then you might be OK using 64 bit SCC. stdio.h functions are supplied and working.

You can either remove the ...
