Hi, I just wanted to report that I got my university Office 365 subscription running reasonably well on CentOS 7 64 bit with CrossOver 17.5, but that I had to install an extra library to get activation to work. To get the applications to display correctly (instead of showing blank windows) I had to install all of the 32-bit OpenGL libraries using "sudo yum install mesa-*.i686" as documented in the Tips and Tricks section. Activation would not work though even after installing Internet Explorer 8, which I later found to be unnecessary. Eventually, I found a tip in the documentation for Office 2007 and installed openssl-devel.i686 to get the 32-bit libcrypto libraries. After this activation worked.
