On the webpage for the digital aviation piper cheyenne it says that fsx sp2 is required, has anyone been able to run it using sp1 only?

I read that to say that it will work with SP1 but has also been designed to run with SP2 as well.The reason why they say that now is because some previous add-onns have had display problems with SP2. That is before patches were issued.So, it will be ok to run with SP1, only. ;)

I read "SP2 is required" to mean what it says - that it's required for this addon to function properly.

Yeah thats how I took it also, But it seems strange that someone would require sp2 for such popular addon. I would try it myself on sp1, but I still cant get the darn thing registered.
