Hello Everyone;

Recently I installed the 64-bit version of Outlook 2013 on my PC running Windows 7 Pro. Unfortunately I have a program that interfaces with Outlook but no longer runs because it was built on a 32-bit architecture. To solve this, I'm thinking I uninstall the 64-bit version of Outlook, and clean install the 32-bit version (both 2013). I also want to archive my entire Outlook library before uninstalling so I don't lose my emails.

Does anyone know if I'll be able to open the 64-bit archive on the 32-bit version of Outlook? If I can't, I'm thinking I either convert the archived .pst file to a single pdf, or I download software to view the archived .pst file. If you guys have any thoughts of those alternatives let me know as well.

Thanks,

Jon
