Hi Jason,
Any version of GridView (32 bit or 64 bit) needs to be launched with a shortcut that has /c on the target path in order to activate the editing and creating functions. I suspect that not being able to edit the definition in 64 bit is completely due to launching the GVWin64.exe application directly, rather than via a shortcut with /c on the path.
I can't speak to the numbers not being calculated correctly for you with 64 bit. With the information you sent to Andrew, the numbers worked the same for me, using the same login date (Oct 17) and comparing 32 vs 64 bit. Though for sure the pink percent field showed 0.26% rather than 27.76% using your 'all sales reps' filter. But when a Summary Filter was used to create the summarization and filter, the correct pink percent was displayed in both 32 bit and 64 bit.
That /c is definitely something that I wasn't aware of lol. I was frustrated by it not working correctly so I just finished reverting their shortcuts back to 32-bit /facepalm.

The data not calculating is most likely due to the not having editing access. It was for a different GV file not the one I sent you.
Thank you
