32-bit MAPI Application and 64-Bit Outlook
Quoting from Microsoft's website:
32-bit MAPI applications are not supported to run on a computer installed with 64-bit Outlook and 64-bit Windows. The application developer must update and rebuild the application as a 64-bit application for the 64-bit platform. This is because a 32-bit application cannot load a 64-bit Msmapi32.dll file.
Can PowerBuilder deploy 64-bit applications ?
If so, which version and build number is required.
