Will WW2 Carrier Ops work on CFS2?
The installs were made for FS2002 and FS2004, and not CFS2. So, I'm not going to make any predictions as to the suitablility of the models. One consideration is that there are tags supported by FS2002.2004 that are NOT supported by CFS2, so even if you were to manually set up the aircraft files into CFS2, you still could have problems.
In short, the add-on was not tested on CFS2, just FS2002/2004.
