32 and 64 bit Access Compatibility

[Joe Y]

I wrote and published an accde file using Access 2007 (32 bit). Recently, I installed Access 2010 in my new PC and set it as 64 bit.

I just realized I can no longer open the 32 bit accde file. I can still open all other accdb files.

I am seeking answers to help me decide if I need to reinstall Access as 32 bit.

- Can I download and install 32 bit Access Runtime in the same machine in order to open any 32 bit accde file?

- Can 64 bit Access publish 32 bit accde file?

- If I open an old accdb file and make changes in Access 64 bit then save, does that make the accdb file accessible only by 64 bit Access? My users are using 32 bit MS Office and installed Access runtime 32 bit.

Thanks
Joe

there's more; however I think that covers enough of the bases...

sorry, looks like you are going to have to find the source file and then re-compile for the 64 bit and keep a second around for the 32 bit,
