Finally getting FSX-SE - it's £5.99 now.

Question is, my 'old' FSX is in C:/FSX and the SE version is going into C:/Program Files (x86) by default - I couldn't see how to direct it anywhere ekse ib the Steam downloader.)

So will I get any conflict problems with both versions on the same drive or should I remove the old version?

Apparently you can run them side-by-side but I've no experience of SE. Not sure all addons will play happily in such circumstances though, especially if you have them installed in both sims at once.
