At least one Windows update or upgrade (or method of applying Windows updates or upgrades) exists that results in a subset of files within the Windows directory being moved to a Windows.old directory.

Complete the following instructions to fix the issue and connect to the localhost:

  1. Copy the four mdf/ldf files in C:\Windows\System32\config\systemprofile to a backup directory (e.g., copy to subdirectory ../RPAC DB {yyyy-MM-dd}/).
  2. Manually stop the SQLSERVR.exe process.
  3. Stop the Nintex RPA Central service.
  4. Stop the Nintex Bot or Nintex RPA LE service.
  5. Copy the four mdf/ldf files located at C:\Windows.old\Windows\System32\config\systemprofile to the new location, replacing the four files that you have just backed up.
  6. Important: Ensure that you copy from the Windows.old directory to the Windows directory.

  1. Restart any services that were stopped.
