Bye Little information ;-) You could try a few things to get more data about what is the point where the program breaks: * Add some log information (write to a log file, not through exception) in the lpr file before it starts the application run. * Add to the main form in the create constructor and in the formcreate event some log information. If the programs doesn't starts at all, then probable you have any problem at binary level. That is usually hard the find. You could ask the customer to run it from cmd prompt. Sometimes it displays some informative message. Once I had the problem that 32bits worked fine in my PC, but failed in customer's system. The problem was that I was using firebird but the customer had installed 64bits version, so the client library fbclient.dll was 64bits and exe 32bits. I copied a 32bits fbclient.dll to the exe directory and everything worked fine. -- Saludos Santiago A. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Nevermind, I checked with -s -a and the generated assembler is the same, with or without the ';' Bye -- Luca ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] stdcall without the ;
I did more than that, I created a DLL that simulates the hardware (it's a phidget I/O board) and it works perfectly, both with the old and the new executable. Thank you for the idea.
