Blu-ray will not install VideostudioX10

What version of Video Studio did you purchase the Bluray plugin
If you were running say 2018 then that will only restore to any newer versions, i doubt that it will restore to an older version.

If you purchased when running X10 then yes it should work for X10, 2018, 2019 and 2020

2010, i purchased and used since some years, even I restored like 8 months ago without any problem. But now after a fresh install I cannot install it any more

You could try re-installing, use the Cleanup tool to remove the program may do a better job in removing the files
Then re-install to try the plugin again.

Otherwise you should contact Corel Support, maybe they can reset the Restore Purchases, although that part appears to be working?
