Has it was hanged I try to kill him in TaskManager but return access denied.
Disable your antivirus as completely as possible and give it another try.
This sort of symptoms - a program that hangs and cannot be killed - is indicative of 3rd party interference with Windows' native functionality. Also, the 1700 error messages are likely a result of Bvckup2 being very crudely "quarantined", which is again something that is done by 3rd party antiviruses, "malware shields" and other "security" software.
"The configuration files are in use by another instance of Bvckup running on a different desktop, the other instance needs to be shutdown first".
This is an unrelated issue, which is resolved and be addressed with the next release. You can simply ignore the message and you should still see the program getting started normally.
