I am considering a new computer and am wondering if anyone knows if the PMDG addons will work ok in this system? Searched, but somehow couldn't find an answer here.ThanksBob LeBoeuf

Yes they work fine with 64bit Windows (I am using Vista 64 and have had no issues), better infact because it removes the out of memory issues assuming you have the ram.

Its actually better to get 64 bit with the pmdg products. As said before, it removes the OOM errors

I run (FS9) the PMDG 737 600-900, 744/F, MD-11 and B1900C/D with no problems with Win7 x64, and the J4100 in FSX. Maybe I'm lucky, but it would appear that both the MD-11 and 744 work better under Win7 x64 than they did with XP x32, plus I get no OOMs (to be fair, I only ever got them with the MD-11).And Win7 looks purty. :)Cheers, Chris Dalgarno
