QuestionIssues with COM-WOW64 Pin

Hi,

I developed an out-of-proc (exe) Server which has both 32 and 64 bit versions.
I developed a client at 32 bit. But when I try to run that client on 64 bit, CoCreateInstance fails giving Class-Not-Registered. For WOW64 bit, I passed CLSCTX option as CLSCTX_ACTIVATE_64_BIT_SERVER. Still the CoCreateInstance failed.

1. How can I call 64 bit exe server from 32 bit client? MSDN says this can be done, but I am not able to do this.

2. If I want to support WOW64 from the server side, what changes do I need to do in the server side? Do I have to install both 32 and 64 bit version exe in the 64 bit OS to support WOW64? Do I need to make seperate regitry entries?

Many thanks in Advance for the help... Smile | :)
