Hi guys. I tried updating as per instructions above but when I got to install the client I get a "an error occurred while attempting to create the directory : C:\program files (x86)\Lockheed martin\prepar3d v3\shadersHLSL". anyone know what the remedy to this is? No I didn't touch that ShadersHLSL folder. I followed to above instructions precisely. Thanks!

Is your P3D installed in a custom location? You must point the update to your current install location. It defaults to program files (x86).

I yep it's just a standard install. Nothing different

Just FYI. I uninstalled all Prepar3D 3.0 before reinstalling 3.1. Perhaps that was overkill, but all addon content was left untouched (aircraft, scenery). The Scenery.cfg, SimObjects.cfg, dll.xml and exe.xml files were also intact; as was Prepar3D.cfg. I only had to reinstall FTX Global and my REX textures. Great job by LM.
