The MSI installer is designed for administrators setting up WhosOn on several computers. It is only required if you’re managing a multi-user deployment, and is not necessary for standard or single users.

To ensure a smooth transition to the latest versions (19.2.195.100 and 19.2.196.100), please follow these straightforward steps:

Start by creating backups of the following directories:
C:\ProgramData\Parker Software
C:\Program Files (x86)\WhosOn Installable

Uninstall the Current Version: Navigate to 'Add and Remove Programs' on your computer and uninstall the existing WhosOn software.

Clean Up: After uninstallation, go to C:\Program Files (x86)\WhosOn Installable and delete any remaining files and folders.

Install the New Version: Download and run the WhosOn 19.2.195.100 or 19.2.196.100 installer (.exe file). This process will also include installing the necessary .net bundles.

Restart Your Computer: Once the installation is complete, please reboot your machine to ensure all changes take effect.

Verify the Installation: After restarting, check that the WhosOn service is running properly through the service manager.

Test the New Features: Try out the chat, settings portal, data, and web client using the links provided in the service manager to ensure everything is working as expected.

In Case of Issues: If you encounter any stability problems, here's a quick fix:
Open the Task Manager and stop all WhosOn services.
Rename the backup folders to their original names.
Restart the services to revert to the previous state.
We hope you enjoy the new version of WhosOn! Should you need any assistance, please don't hesitate to reach out to our support team.
