I was using studio community edition succesfully before.
After that i installed Platform version and it also went ok.
But after license expiry of the platform edition, i have uninstalled the version completely and trying to install and use the community edition yet again. But this gives a license violation.
As i already had uninstalled the platform version earlier, so i dont have the regutil.
I triend installing the platform yet again, but regutil deactivate is complaining that the license is not present
If you had trial code before(or a license key) you cannot go back to using CE(Start free). You’re right, contact the support team for a trial extension.
