Update from 7.4.17 to 7.5.4 is causing Simsounds to close

[chasbruce]

Hi John, I'm using MSFS 2020 + Simsounds 4.3 (https://www.simsounds.de/home/) + FSUIPC 7.4.17.

I updated FSUIPC to 7.5.4 and Simsounds started to close (see event viewer details attached).  

I'm sure it is FSUIPC because Simsounds closes every time the FSUIPC screen appears when I load MSFS, so I re-installed 7.4.17 and I no longer have the issue.

Simsounds has recently announced that it is no longer developing its software, in case this is relevant.

The FSUIPC log attached as well, although this is the last session when everything was working again.

EDIT - another program, Opencockpits SIOC v8.1B8, which has been rock solid for a very long time, also registerd in event vwr a stopped responding immediately after I installed 7.5.4

Regards

Charles

The log file you attached is from 7.4.17, where you say everything is working. Although that log file does contain errors.

7.4.17 is also quite old now - there have been 6 release since that version. You should update more often....

One change that was introduced in 7.5.0 that could affect some third-part add-ons is the offset that holds the sim version (0x3308), Some add-ons expect a value here on start-up, and prior to version 7.5 this was always set to 13. With the introduction of MSFS2024, this offset is now only populated once FSUIPC has a connection to the FS so that it can determine the version being used. For add-ons that need this offset populated earlier, you can add the following ini parameter to the [General] section of your FSUIPC7.ini file:

     init3308=13

So please try that. Any issues, please set logging for IPC Reads and IPC Writes and show me / attach your FSUIPC7.log file. Also, please always exit FSUIPC7 before attaching logs.

Many people use SIOC with FSUIPC - I would have expected a lot more support requests if there was an issue here.

If you still get issues with that change, after saving the log file from 7.5.4, can you also please try the attached version below, which is 7.5.3 (just rename your current FSUIPC7.exe and save the attached to your FSUIPC7 installation folder). Also show me / attach the log file from this version.

Hi John, thanks as ever for the great support.

Yes I know that is what has always been recommended by FSUIPC, and justifiably.  But if there is one thing I have learnt over the last 15 years of building a full-sized sim is that what matters most is stability.  When you have older hw and sw like me, the great thing is when it all works, you have reached sim nirvana.  The problem with updates is that very often something breaks and, in my case with older stuff, the update is probably not needed anyway.  For those with the latest and greatest, yes you have to.

For this reason, I will stay on 7.4.17 for the time being (all is working), but if/when I need to update I will test again and follow your very helpful guidance.
