Hi,
after updating to 9.1.26 from 9.1.23 neither rrClient nor rrClientconsole work anymore. Both crash with a segmentation fault. The logs are not really useful to be honest.

This is on Rocky 9.7
Any idea what could be causing this? We're going back to .23 for now.

Hi

 

Is there a .rrdmp9 file in folder RR/sub/log/?

If there is, please upload it via www.RoyalRender.de/upload

 

I will take a look at all changes that have been made to the rrClient to see if there is one that can cause the crash.

Hi


The issue was found.
Please download the installer www.RoyalRender.de/download/RoyalRender__9.1.26a__installer.zip
Then rename the folder installer/files/bin/lx64 into lx64_test and copy it into your RR folder.
Execute the rrClientconsole to verify that it works.
