Years ago I had this installed, but I have since built a new machine and did get a new OS hard drive.  FSX, p3d v4 and 5 was on D and E at one point or other over the years. So, D and E have been brought over to the new machine.  The problem I am having is PMDG 777 install thinks there is a p3dv4 and p3dv5 pointing to the same v5 directory and so I don't have gear and cannot click anywhere in the VC.  PMDG says it's EMT that's causing the issue.

v4 and 5 was installed last Fall when I built the new system. I tried uninstalling v4 and PMDG, but that didn't help.  FSX is not installed.

I submitted ticket to EMT, but they haven't responded.  I tried searching around, but cannot find anything.  

chances are it's a left over registry entry. Use a program like regscanner (free) and search for any entry with p3dv4 and 5. You might find one that's pointing to a wrong location.

Also get something like Revo uninstaller (free) and let it do a deep scan for EMT.

You mught google to see if there is a way to identify and list all symbolic links and junctions in a table, you might spot a bad entry there.

That would be my first steps.

Good luck,

Vic

I ended up formatting c and starting over completely.  

Sometimes that is the fastest and easiest solution in the long run.
