Yeah BilaL Aziz, I installed windos xp, then 7, and actually optisystem released the project browser, never used this compatibility mode, the interesting thing is that you have solutions here at the moment, a Tip If your notebook, for example has a 1Terabyte you repartition your HARD DRIVE, for example creating a 100 GB partition, and install windows xp, for example, only a little more work, then install the optisystem 7.
