PFM won't start because of missing SimConnect


when I try to start Preflight Manager 1.0.6387.29299 I get the following message and the PFM won't start.

SimConnect Client v10.0.61259.0 Not Found
The Application WIll Now Quit.

I have Prepar3d v4 (latest version) and the Prepar3d SDK installed.

I googled for the SimConnect version mentioned in the message, but couldn't find the appropriate version.

Any ideas?

    Have you tried downloading and installing the latest PFM version from the website? This one should be optimised for P3D v4
  • Hi,

    I'm also running into the same problem. I also got Prepar3d v4 but no Prepar3d SDK.
    I modified the Registry to map FSX addons (which I know, working with 64 Bit) into the Prepar3d installation.
    All FSX scenery addons and PreparV4 addons I'm using are working as expected.
    So what could be the reason for your PFM running into the "SimConnect Client v10.0.61259.0 Not Found" error?
    I got the newest tool version and also installed it without Anti Virus and with Administrator rights.

    Best regards,
