This has no doubt come up numerous times, but i haven't found an answer that works yet...

 

I can't get any version of Simconnect to install on my P3D machine.

 

Am I missing the obvious?

double-click these and they should install simconnect reliably:

 

C:\Program Files (x86)\Lockheed Martin\Prepar3D v3\redist\Interface\ESPv1\SimConnect.msi

C:\Program Files (x86)\Lockheed Martin\Prepar3D v3\redist\Interface\FSX-RTM\retail\lib\SimConnect.msi

C:\Program Files (x86)\Lockheed Martin\Prepar3D v3\redist\Interface\FSX-SP1\retail\lib\SimConnect.msi

C:\Program Files (x86)\Lockheed Martin\Prepar3D v3\redist\Interface\FSX-SP2-XPACK\retail\lib\SimConnect.msi

 

 

I've heard of simconnect being mysteriously disabled after some other installation of some other app, but it seems so far in these circumstances running the .msi installers always repairs it.

Hi Phil. I feel your pain!

My Windows 10 was from a Windows 7 upgrade and produced many problems over the last year including SimConnect problems! Third party planes and ultilities like ezdok wouldn't work correctly etc. The list is hair pullingly frustrating. Also I had a hodge podge of P3D iterations...3.3 with 3.3.5 content etc.

My only solution was to buy Windows 10 Pro, (Home would have sufficed too), and perform a clean install of the OS, along with a clean install of 

P3D 3.4.9.18400

Seems extreme, however it's working extremely well!
