Well I for one hope that everything is going to be ok for FFS and any others in the flight sim community. We need all the outlets available, so hoping all will be well.
If you are running FSX and the software is compatible with FSX then it should install quite happily. Likewise, if you are running P3D and it is compatible with it then yes again.
Happy Birthday Andrew, I hope it has been a memorable day for you and that your friends have visited plentiful supplies of Castlemaine XXXX or lashings of Fosters on you. As well as a humongous cake.
All the best mate.
