Hi.

After reinstalling my PC i had to upgrade a robot system from 5.10 to 5.11.2003.02.  
I did not had rw 5.10 after my reinstall.  
After upgrading my system i cant use any socket instruction. I tried to add socket option but it is not there anymore. I now that socket is now a part of standard configuration.  
Is there an other option i have to add before socet is activated.

Strange. I changed the RW to 5.11.1033 and it works. Changed it back to 5.11.2003.02 and now it works.

Don’t make any sense but won’t think more about it. Now it works
