Are any of you doing this?
I have FSX running very nicely on a new machine I just built a couple of weeks ago.
But I would really like to use my PMDG 737, so was planning to install FS9 as well.
I would not install to 'C' but obviously a load of FS9 files are going to go to 'C' no matter where I install it.
Only one hard drive in the machine at the moment.
Just wondering if installing both of them could cause problems or conflicts.
Any advice or hints appreciated...
No it won't.
No, well, it shouldn't. Just make sure you have suffecient space and you will be fine. I'm running both and I have no problems
