Can't open Dreamweaver 2020 - error 2

[KamilK]

Hi for some time now I can't launch Dreamweaver on my Macbook Pro. 

The error message is: " The following Javascript error(s) occurred: Unable to open script file..."

I've tried uninstalling all adobe products, clearing cache nothing helped. Did anyone had a similar problem and found a solution?

Thanks,

Kamil

1. Uninstall Dreamweaver and the Creative Cloud Desktop app.
2. Use the Adobe Cleaner tool to wipe old files from your system.

3. Then re-install CC desktop app followed by DW.
