Installing Pro-Q 3 after buying Pro-Q 4
I have a producer I work with that uses Pro-Q 3. I bought Q4 assuming I could install Q3, but the license manager tells me I have entered a license for a different FabFilters product. Ideas?
Thanks-
isaac.

Hi,
I am in the same situation, but with Ableton and Windows 11
