I get the followong error when uVision V5.31.0.0 starts: Cannot download vendor lookup file https://www.keil.com/pack/vendors.idx - Continue check for update with previous copy Check for updates error: Cannot download www.keil.com/.../vendors.idx, Cannot modify read-only attribute.
This stops further work. Any clues?
I found the remedy:Remove the read-only attributes in C:\Users\localadmin\AppData\Local\Arm\*
I had the same problem. Thanks for the solution!
