I own both the MD-11 and the J-41. I had both running perfectly on my old FSX install but I recently had a hard drive crash and had to reinstall FSX. After getting FSX up and running again, I am having problems reinstalling the PMDG planes. The J41 installs fine and seems to fly ok, but when I try to install repaints, it says there is no aircraft.cfg found. The J41 also did not have me activate it at any point in the install. On my old install, it had me activate it in the FSX preview window. I then tried to install the MD-11 and that proved just as bad. The plane seems to install fine but then after the installation it has me install the V2008 redistributable or something like that. Ir gives me the options "repair" and "uninstall". I click repair and then it gives me an error that says there is not enough space on the hard drive for it which is not true because there is something like 500 Gb free. neither of the Service packs will install either. What is going on guys?

Please sign your full name to posts in this forum.What is going on might have something to do with the hard drive crash. Are you on a new hard drive? Reinstall OS okay?

Ah yes I am sorry I forgot my name. I am on a new hard drive but I have FSX on a seperate drive than my OS so now I did not have to reinstall the OS. Brand new hdd and FSX installRyan Rezabek

My guess is you may have installed FSX on a new hard drive, other than the system drive, but the registry entries on the system drive are still pointing to the old information. Try the control panel removal of programs and once cleaned up then hopefully the installers will work.
