Hi John;

   The CRYPT32.dll (CL.dll) is not part of PowerBuilder. Sounds like your using a 3rd party product. I would advise you to contact the vendor on this issue.

Greetings, John -

You've given the Community almost no information to help you diagnose the issue. I'm not claiming that I can help, but I doubt anyone else can with what little you've told us.

What version/release/build of PB are you using? What "emailing function" are you using? Is this function in an external DLL or in another PB (non-visual?) object? Did you write the function you are calling? If not, who did, and have you contacted the author/vendor? Is the PB app compiled for 32-bit or 64-bit execution?

crypt32.dll and cl32.dll are Microsoft-supplied DLL's that provide cryptological functionality. Are these available on the user's PC? What version of Windows does the user's machine have installed? Is the version of these DLL's on the user's system the same version that you are using on your development system?

Please also recognize that it is now the weekend and many of the people that help answer questions on the Q&A forum may not be online or otherwise available to respond as quickly as you would like.

Regards, John
