In the last month, I’ve been testing new versions of my main Windows apps. I’ve been working with the shipping version of Office 2010, which will be released to the general public next week. I’ve also tested the Photoshop, InDesign, and Dreamweaver components of Adobe Creative Suite 5. And, for the last day, I’ve been testing Lightroom 3. I’ve tested both the 32-bit and the 64-bit version of Office 2010 on both 32-bit and 64-bit versions of Windows 7. I tested the 64-bit versions of CS5 on 64-bit Windows 7. I have tested the 32-bit version of Lightroom 3 on 32-bit Windows 7, and the-64 bit version of Lightroom on 64-bit Windows 7.
All tested configurations worked reliably, with the exception of 64-bit Outlook 2010. With that program, I experienced application crashes when it was trying to render HTML in the preview window. I think that it might be related to an interaction with Norton Internet Security, but I can’t prove it; while I was trying to diagnose the problem using Outlook safe mode and turning off NIS, it went away. I notice that Microsoft recommends against using the 64 bit version of Office 2010, and recommends the 32 bit-version for all operating systems including the 64-bit ones. Unless you have unusual requirements, I suggest taking that advice.
