SLHelper errors after upgrading to DataMiner 10.2.2

After upgrading to DataMiner 10.2.2, I got 2 "failed to launch SLHelper" errors.

Is there anybody who would know what caused those errors?

localhost Error Unexpected exception: (Code: 0x80131500) Skyline.DataMiner.Net.Exceptions.DataMinerException: Failed to launch SLHelper (60s)
at SLHelperTypes.HelperWrapper.Launch(HandleMessageCallback messageCallback)
at SLReplaceLauncher.Replacer.Launch(String[] args)

Since v10.2 and v10.1.12, NATS is now used for communication between SLNet and SLHelper.
Is it right after the upgrade or only when an action is done? E.g. when a report is generated in pdf format?

I would advise to have a look at the logging, however the question is still when you get the exception. I would suggest to consult with your Skyline contact to have a look at this. I.e. to check the logging, generate a PDF report as test, to see if SLReplaceLauncher didn't crash during the upgrade, to see if SLHelperTypes.dll is the correct version, ref. RN30845 and RN31308.
