Kindly I need help to launch CATIA V5 from OC platform, I don't know what is the configuration to run CATIA V5(Ex2-CATIA educational heat EAR2 configuration) from OC connector, ​​​​​​​
here are some steps I tried but I did not work 

1- I removed my server from DSLS and license from my device

2- I tried to launch my CATIA V5 standalone​​​​​​​

3- CATIA failed to work without license

4- I logged in 3dexperience platform and installed V5 connector

5- I launched CATIA V5 from OC

6- CATIA V5 worked successfully even when I removed server and License

6- I repeated the same steps for 2 other training devices ( they had no licenses) and attempt failed

7- I tried to setup DSLS server and create server without license but these steps did not help

• Do i need seperate License for CATIA V5 to run it from OC?
