CTD in Win 8.1

I migrated FSX (SP1 and SP2) to Win 8.1 and I am getting the following two errors (from the event log) followed by a CTD.  Has one seen this and know how to fix ?

1st Error

Faulting Application Name: FSX.EXE

Faulting Module Name: PMDG_737NGX.DLL

Exception Code: oxc0000005

2nd Error

Activation context generation failed for "C:\FSX\Modules\FSUIPC4.dll.  Dependent assembly Microsoft.Flightsimulator.Simconnect........<additional information>......could not be found.

There is much more information in the log but copy | paste does not seem to work in this forum and I don't see an option for an attachment.  Please let me know if anyone has this and knows how to fix.

Thanks,
