I am trying to install the Service pack 1c, but it keeps telling me that there is no version of PMDG 737-8900 NGX detected.

I've copied the update into my PMDG 737 folder inside FSX but it still gives me the same.

 

I need to install this update before I can install FS2crew.

 

What seems to be the problem?

Does anybody know how to solve this?

 

Thanks and regards

Try registry repair tool.

Thanks, I will give that a try

Failing that, re-install the NGX from scratch. If that STILL fails, submit a ticket...

are you running a programme called regcure ?
