Hey,

so I was reinstalling Prepar3d because of some issues. Then when i log in again, I install all the addons which was installed before. Then when I choose the PMDG 737 NGX 800/900 it says "unable to create work files, run Prepar3d as administrator" An Ive tried to install the aircraft up again but still the same problem. 

I also tried to update the AIRAC data on Navigraph.  It says that the aircraft has the newest AIRAC, but when I check the FMC, it says AIRAC cycle 1108. 

Are you running P3D with admin rights?

Welcome to the PMDG forums, please note their rules ask that we use our full names on all posts.

Yes, it's  running with Administrative rights.

 

Hello again, I just found out the problem. So no need for more help.

Hi

I have the same problem "unable to create work files, run Prepar3d as administrator" on P3DV4 after installing the PMDG 737 NGX "successfully". Starting P3D with a right klick on "start as administrator" causes a program crash.

Well - it's not a crash, but the program doesn't start and shows this error message:

Invalid location
Cannot save the archive 'prepar3D.zip' to the folder ... please chose a different folder.

This is a P3D issue, then. Sounds like you have some permissions/shortcut issues on your computer.

Try manually browsing to your P3D location. Find the P3D.exe, right click that, and select Run As Administrator. Does it work?

The problem with AIRAC data got fixed by going to navigraph.

Fixed it by doing this:

Navigraph - Addon Mappings - Scan

I found out that the PMDG folder was found in the folder. 

I‘ve read that many people coming from P3Dv3 upgrading to v4 manually edited their path in the navigraph manager. Although they better should delete the mapping and scan it again for PMDG. Then it shows P4D instead you f P3D and everything workes/ed for them.
