It appears you have an error in system.xml file - line 7 character 77. Is this the first time you have used this virtual controller/system? ---

This is the story, I have a flex arc cell, the station has been built by ABB, Station was built with RS 5.15 and RW 5.15 , I now decided to get into offline programming so my RS is 2019.3 and I have RW 2019.2 and RW 5.15.16, We had issues with being able to add a weld instruction using the AWPP (2019.3),. ABB told me to build a new station with all the same options as in old station and then copy the Internal/RS from the new station into the old station. I did as i was told i now can add a weld using AWPP but now my Virtual Flex pendant doesn’t work and I could not get the simulation to work as of yet. See attached pictures of errors i’m getting. ![image.png](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/2X/4/4324dfc67e074282ce63f7777b7f8bbef6629564.png) ![Screenshot (4).png](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/1X/563369bb51510317459f0b19c917c3c26f73c0a9.png) ---

I have found if Write Access is given to RS **before** starting the virtual pendant app troubles are almost always encountered. ---

I do not ask for write access,all I do is click on the Virtual flex pendant in controller tab and i get the error. ---
