Reinstalling ROF question

[+Stary]

I'm considering buying few planes during the current planes-sale, but as I haven't yet reinstalled ROF after system reinstall, here's my question:

 

I have full (program files folder) ROF folder on my backup drive (as it was before reinstalling 7) -is it possible to install ROF from DVD and then simply copy and overwrite the files using my backup install..? I don't fancy redownloading whole updates given my uber-slow internets and as I have some limited free time during easterns...

I read on the RoF Forums that it should work!
