So I recently download Rhino 5 and Vray for a new computer. The 32 bit version runs fine, but the 64 bit version is have issues. I can open a new blank file for the 64 bit version and vray and everything is working fine no issues with drawing or rendering. But, when I open a site plan in the 64 bit version it crashes. The odd thing is I can open the file on the 32 bit version but as I said, the same file causes the 64 bit version to crash. Do you know how to trouble shoot this issue?
