After hours of trying to find the solution I’ve found out that this is IIS settings issue.   This issue was caused by MVC 2 installation, unfortunately it’s uninstall didn’t help.

To fix this:
1. go to IIS Manager
2. go to the application pool instance
3. click advanced settings
4. Under Process model, set Load User Profile to true
Hope this will help!
