Hello,
Regular exceptions, those raised with the "raise" keyword are always
trapped by try..except blocks but you have to make sure that EVERY
method in the DLL that is called by the host exe has such a construct
so as not to let the exception escape.
However, there are exceptions that come from the FPU and that arise
when doing floating point maths. Those, in a DLL, are not trapped by
the try..except blocks and are passed back to the host exe,
effectively crashing them.
If you want to trap them, you have to add a special unit in your DLL
project, as explained in this issue:

I read quickly the las post and seems encouraging. I'll try it in my UDF
(64bit, windows, Michael is right) and report any discrepancy but not
before next week.
Look for the last comment, it works fine here
Regards
