P3Dv4.3 installations requirements

[cirurgiao]

I bought P3Dv4 because it's 64bit and begin buying addons that I had installed in FSX (which I kept in my pc but never run it again).
Upgraded my pc with a 1TB Samsung SSD and reinstalled OS there and got 2 1TB Samsung SSDs (new) where I will install P3Dv4.3 in one and P3Dv4.3 Addons in another.
Do I need to have any kind of program before installing P3Dv4.3 or all I need is in installer? (I don't want to reinstall FSX if this can be avoided)
Tks and sorry if it seems a dumb question
