"Apache.exe could not be replaced" message during installation

Cause:

This happens when the Giga Vault Storage web server service (which uses Apache) did not exit properly when the previous installation of Giga Vault Storage service was deleted.

Resolution:

Open the windows task manager and kill any instances of php and apache that is running. If this does not help, open the Control Panel->Administrator Tool->Services and stop the Giga Vault Storage Web server service and then proceed with the install.
