Two week back i also had the same issue while upgrading,
i added the User to the Performance Monitor Users group then it's working fine without any error.
maybe try it.
If the service account user does not have administrator privileges, you need to add the user to the following groups in Computer Management > System Tools > Local Users and Groups > Groups.
- Qlik Sense Service Users
- Performance Monitor Users
If not already done so,
1. create and new user with Administrator rights specifically to run the Qlik Services
2. Assign this user as the logon user for each of the Qlik services, EXCEPT for the Qlik Sense Repository Database service.
3. Restart all services.
4. Log off and login as the newly created user and repeat the upgrade.
Hope this helps
