Last update Art. 2020

I installed the last update (Nov. 10) but I can´t open the program… what can I do?

Thank in advance…

On which platform ? macOS or Windows ? which OS version ?

Windows 10… but I could solve the trouble… following your solutions, I think there were temp files… I deleted all, not just abvent folder… and everything is fine now… thank you!!!..

Ok, thanks for letting us know. Do you remember which files you have deleted exactly ?
