Error -16034: Non-admin Cannot Unregister Solution Extension

Last Modified: November 16, 2020

The Package Builder solution extension (.pbs) could not be unregistered because the current user account does not have administrator privileges.

Why does this error occur?

When installing Package Builder, the *.pbs file extension is registered with Windows to allow Package Builder solution files to be opened in Package Builder by default. This registration is removed when Package Builder is uninstalled. Unregistering requires administrator privileges.

How do I resolve this error?

Uninstall the Package Builder package again with administrator privileges.
