When you launch GSX Monitor Remote Client interface MSI Installer via Windows Explorer, it may not be running with Administrator rights by default.
Depending on how the User Account Control (UAC) is configured for the current user, any installer will be run with restricted permissions unless specified otherwise.
- Internal Error 2503.
- Internal Error 2502.
How to solve the Issue
The GSX install package may not have been run with elevated permissions. This will prevent it from having full access to the Windows services or registry causing a partial installation.
What we need to do is launch the installer as Administrator.
- Right-click the installer package.
- Select Run as administrator.
- Select Yes if prompted to confirm.
