If you see a message such as the following while installing or upgrading:

"Error opening file for writing: C:\Program Files (x86)\Spot Flux\Services\IPC Service.dll"

One of the Spotflux services is likely still running, which is holding a lock on the file. This will prevent the install updating the file. Stopping the service(s) will free up the file:

  1. Open Control Panel
  2. Type "services" in the search box
  3. When the result appear, select "View local services"
  4. Look for the services with the name "Spotflux Connection Manager" or "Spotflux Update Manager"
  5. If either of these are showing "Started", select them one at a time and click the "Stop" button.
  6. Once the services are stopped, you will be able to reinstall Spotflux.
