I already bought this nice piece of software some months before 😦 to run origin under linux – and: it works 🙂
It was (relative) easy to get it working! I had only problems with the greek fonts and I simply copied those into linux – using suses font management.
Now I got a license key. To install it under ubuntu try:
sudo dpkg -i crossover-standard_7.1.0-1_i386.deb
to install windows software under linux
