Installed MSFS rel 15. Updated FSUIPC7 v7.4.12 and now Fsuipc7 won't auto start in MSFS 2020


Recommended Posts

As the topic says.

Any ideas what could be wrong?  The previous version was working fine.

The updated Installation seemed to go fine except for where the documents were stored.  Here's the log:

John, thank you for the quick response.  I loaded the beta version C and this time saw the plus + sign and turned off .bat file option.  So all is good now.  

Should I reinstall the non-beta version?

Thanks so much

Yes, please install the latest official 7.4.12 as there are a few updates from the beta (and also from the 7.4.12 version I provided for SU15), including documentation.

Having lots of issues as well i updated yesterday to the latest version and found it strange that even when registering my details it did not let me finish the install with out skipping the reg details even though it did put them in. since then FSUIPC don't auto start with MSFS and my controls on PMDG do not work, they show in the button assignments under pmdg 737 profile but no switch movements when used. is there a link to get the older version back for now.

I can't get FSUJIPC7 to autostart after installing ver 7.4.12. There is no FSUIPC7 entry in my exe.xml file.
MSFS.bat attached.

Why have you installed FSUIPC7 under your Documents folder:

start "" "C:\Users\Al\Documents\Al's Flight Simulation\AddOns\FSUIPC7\modules\FSUIPC7.exe" "-auto2"


Re-install in a non-windows protected folder.

If using the MSFS.bat method does not work for you (and I have no idea why this would be), then switch to using the EXE.xml method in the installation process.

As I have said many times now, if FSUIPC7 does not auto-start using the MSFS.bat auto-start method, re-install and select the EXE.xml method instead.

Hmm... Interesting, I have been installing FSUIPC7 there for years without a problem.

Until today I did not realize there were install options between using MSFS .bat and the EXE.xml file. I guess previously the installer defaulted to the EXE.xml option which I use, but now defaults to using the MSFS.bat file.  I only included my MSFS.bat file above because I saw you had requested it from a previous poster -- I didn't realize that was an install option.

So I have selected the EXE.xml option and all is working now, thanks very much for your help.

Thanks for the hint for installing the . exe-file. 

The option is not clearly to see while installing FSUIPC.

Yes, the MSFS 2020 simulator update has been released. 
Using the Pilot2ATC program, I was forced to install FSUIPC7 v7.4.12 . When starting the simulator in the usual way, FSUIPC 7 v7.4.12 did not load. At first I couldn't understand the reason. 
I read the forum, it turns out that the developers have changed the launch method. I am pleased with the work of the developers who thought about the users in advance. Everything started working faster. Good luck to you in your noble cause.

I start to have some similar issue where the MSFS is starting as normal but FSUIPC not. I'm currently on version 7.4.12 and if you need the log file is attached.

Have you read the documentation on auto-start, or read this thread?
I have now explained the changes to the auto-start in v7.4.12 many times now...once again...

The default auto-start mechanism in 7.4.12 has changed from using the MSFS EXE.xml file to using the FSUIPC MSFS.bat file or the MSFS desktop link to that file installed by the FSUIPC7 installer. If you are not using the MSFS.bat file or MSFS desktop link to start MSFS, then FSUIPC will NOT be auto-started.
If you are using that file/link, then I do not know why FSUIPC7 isn't starting - check the MSFS.bat file and find the FSUIPC7 start-up line - does that look correct? Try pasting that line in a cmd terminal - does that work or report an error?

If you cannot get the auto-start via the MSFS.bat file working, just switch top the EXE.xml method. To do this. re-run the installer and in the component selection page open the auto-start options, deselect the first option (MSFS.bat) and select/check the second option (EXE.xml). This will then revert to the EXE.xml method of auto-start which was the default in earlier versions.
