Is MS office 64 bit compatible with Delphi 6 applications?

Question

My application is developed in Delphi 6, The application have some document management modules which works fine with 32 bit MS word, but not with 64 bit MS Word.

A type library called WORD_TLB is used to access the MS word functions from delphi code. Can i generate a new type library or something else to make the application work with 64 bit MS word? Is it even possible for a Delphi 6 application to work with MS WORD 64 bit?

Please suggest.

Yes, it is possible to automate 64 bit Office applications from a 32 bit Delphi process. The Office applications execute as out of process COM servers and so the mismatch of bitness is not an issue.

I'm sure that you do have a problem, but that problem is not due to trying to automate 64 bit out of process COM servers from a 32 bit process.
