Hi Audrey, thanks for weighing in. Do you have the same date on your 64-bit GVRW DLL still? and you can actually write to a table using the 64-bit version?
Do your installers have the April 22nd signed date (properties > digital signatures tab) on them or something even newer than that?
From what I can tell, the newer versions of the installers were used to install in this case, but it is confusing when you have multiple different copies of the same release out there.
