Hello everyone.

With STM Utility Flasher I can programm chip so I think It is a windows problem.
I run with "run as administrator". I have Arduiono on disk C, on disk D and still the same problem.
Programmer - ST-Link V2 clone, after ST Utility firmware upgrade and with old firmware (when Arduino was ok). It doesn't matter.
After 2 days I have no more ideas, help me please.
I apologize for not being word-perfect in English
