[Solved]Cannot install on P3D v3.3.3 !!

[markos]

Hi Markos,

Yes, it is compatible but sometimes things can get a bit whacky with FsP and P3D. Did you have a fresh installation of P3D or did you update the client only? It doesn't happen with every pc but unfortunately sometimes it's necessary to do a complete uninstall of P3D, re-install P3D and then install FsP.
The topic was also discussed in this sticky:

I had a fresh installation of P3D. It is the first time I use it. I get the same error as per the link above.
The FsP installer I use is the latest one.
It is very difficult for me to re-install P3D because I have already installed MANY add-ons!!
Is there any other workaround?

Otherwise, can I get at least a refund, because the problem is not from my side! 
Many thanks!
