After a crash I now have different Hard Disk positions. All the FSX stuff is intact. I have managed to reinstate all except PDMG which on trying to reinstall the following occurs. It is unable to locate fsx.exe and the readme says: This installer will search for your flight simulator installation as itis reported by the registry on your machine. If you have moved your flight simulator installation, or if you deleted it and re-installedin a new location without updating the registry on your computer, youmay be told by this installer that it cannot find your MSFS installation.If this message is displayed, you must manually navigate the installerso that it points to your default MSFS installation directory, or thisairplane will not install correctly.How do I effect the navigation, the installer closes.RegardsKen Ellis
