Calling 64 bit com wrapper from 32 bit PB application

Hi

Currently running a PowerBuilder 12.5.2 classic application and wondering if it is possible to call a 64 bit COM dll from the application?

The reason for asking this question is I may have some clients going to 64 bit version of Office and we currently use redemption as the interface to outlook.  64 bit outlook requires 64 bit redemption which in turn requires a 64 bit calling application.

Thanks in advance
