FSX Simconnect apparently disappeared after upgrading to W11

Recommended Posts

Hi All,

I have a carefully managed FSX setup composed of FSX SP2 (no SDK), ASN, FSC, GSX, FSUIPC, FSXGET, various PMDG planes and other utilities.

Quite recent installation, less than one year, as my old FSX-PC crashed after many years of service. All is installed on a separate SDD to avoid issues and keep the FSX world clean.

My setup has been working as a charm until last Saturday night when I updated to Win11. After the update FSX works well and the other individual components appear to be working as well, BUT it looks like SimConnect has disappeared!

FSUIPC logs that is not finding any of the supported versions, ASN connects to FSX but then throws an exception because "no compatible SimConnect library found", i suspect FSC10 will do the same.  

I had at hand all of the SimConnect.msi kits, and tried to install them one after the other: it looks like the installation starts, I see the eula splash screen, but after the (supposed installation) i do not see any new Simconnect file either in WinSxS or other folders on the PC disks. Also tried to reinstall FSX-sp2 to get it from there. Nothing.

The only Simconnect I see on the whole PC is the one associated to FSXGet, it is visible both in WinSxS and the FSXGet directory but has a name like microsoft.flightsimulator.simconnect.... And in fact FSXGet works with FSX so I can track the flight on GEarth as usual. 

Already tried the known actions: review AV exclusions, UAC, permissions, ... 

It looks that just upgrading to W11 made Simconnect to disappear silently... and now it looks it cannot be installed the ways we are used to-

 

Any hints on how to solve ? Did some of you already migrated to Win11 without finding this issue ? 

 

Thanks in advance for any support or hint !

Kind regards,

Aldo Borrione+

Could it be due to a permissions issue in Win 11? 

Also wonder then if FSX SE can be successfully installed in Win 11.  That is the only fallback I know of for FSX as I am pretty certain FSX w/SP's can no longer be activated.  Any particular reason for early Win11 adoption?

Hi Frank, 

thanks for the prompt answer.

Permissions: maybe, in order to avoid known potential issues when installing the simconnect msi files I disabled the W11 security/AV/Firewall features, I do not expect permissions as set on the dedicated FSX SSD should have been changed just due to the upgrade (there are 5 other disks on the PC.. would be a mess if permission have been changed during the update). However good point to track in further investigations.

FSX has remained activated, I did not get any message at this regard so far. Don't know if FSX SE can or cannot be installed in W11

regards,

Aldo Borrione

Are you getting in to FSX, or instead having trouble with addins?

FSX works, even though I still could not perform long flights. FSUIPC disappeared from the Addin Menu, GSX related tuff is still visible, unsure they use Simconnect.

An update after 4 hours of debugging work: tried to install the simconnect msi packages from the admin command line. Apparently they installed and are now visible in WinSxS, as they were in the former W10 environment (I mounted a w10 backup image in explore mode to compare side to side the folders' content).

Nothing changed, simconnect still reported as missing

Then I restored from a backup image the whole FSX SSD (restore mode) and the relevant folders in C:\Users\User\AppData.... (copied one after the other) to realign with the files restored in the FSX SSD. Nothing again, everything works as individual component but simconnect stil reported as missing.

I have no further ideas at this time...
