The operation cannot complete because of an unknown error [CANT]

"Solution for Adobe Illustrator. Regarding the problem...

"The operation cannot complete because of an unknown error. (CANT)"

The problem is caused by some files in the directories.

"c: \ Program Files \ Common Files \ Adobe \ UXP \"

In Windows 10 (X64)

Rename to "c: \ Program Files \ Common Files \ Adobe \ 00UXP \"

(In this way they are not erased and you can return to them, for if other programs fail)

It contains the routines for the start screen and new documents of the different Abobe programs.

Changing UXP to 00UXP worked like a charm!! This actually works for me!!!
