Running Windows 10, had the Studio Link issue too (Affinity Publisher -> click on the Affinity Designer logo ('designer persona')... Studio Link could not find Affinity Designer... even if you're 100% sure etc).
I run the latest versions of all Affinity programs (1.7.1.404).
What worked for me to fix this?
- Updated all Affinity programs
- Closed all programs
- Opened one by one all Affinity programs as administrator (right-click on the logo... go for 'run as administrator'), one at the time to have all 3 open as administrator.
- Click Designer persona in Publisher... worked.
Good luck!
Fred
