I tried to install edrawings 2015 on a vendors machine. It's win 7 64 bit sp1 with plenty of room and memory. I get an error saying edrawings needs win 7 32bit  sp1 for it to install (not verbatim but close). I downloaded the supposedly 2015 64 bit version. I checked and he has both program directories for 64 bit and 32 bit with both programs in them. Any help is appreciated.
