Hi,

I have been doing some testing on Excel 2010 and testing out the 32 bit
addinn application(which contains vba addins, c++ libraries and VB
libraries). And this seems to be working fine with 32 bit version of office
and as expected its not working with 64 bit version one.
Can some one confirm that to work with office 2010 64 bit, any client
application (all dependant components-vb,vc++,vba etc)should be converted to
64 bit? Or will there be a support for 32 bit application by default when 64
bit Office get released?
Any suggestion here will be highly appreciated as we need to plan to support
our internal and external clients when O2010 get released.

I have posted the same query at Office section also.

Thanks in advance!

In Excel 2010 64-bit VBA is 64-bit so the VBA will automagically be
converted.
All non-vba dependent components will need to be converted to 64-bit.
Windows API calls may need to be changed

Note that there will not be a 64-bit VB6 compiler available, so any
VB6 components will need to be rewritten (convert the VB6 to VBA would
be easiest).
