My public library has both Overdrive and 3M Cloudlibrary. The Cloudlibrary app requires the most recent version of ADE. However, it crashes when I try to fulfill an .acsm file. When I was trying to close ADE through task manager, I noticed that it was 32 bit, but my laptop is 64 bit. To work around this, I have to deauthorize ADE 4.5, then reauthorize 3.0. I don't like having to use multiple versions to accomplish something so simple. I was thinking because it is a 32 bit program that is why it isn't working with my computer. Does anyone know if there is a way to download a 64 bit version of ADE 4.5?
