Remove Version 9 Registry Settings
Version 9 and below would use the WOW6432Node to set the server address. If you upgraded to version 10, this registry hive is locking those particular settings.
Here is a PowerShell script to read and remove that entry from the WOW6432Node folder for a single computer with a confirm command switch. It is safe to remove this entire hive after version 10.
#Write the old server address to screen the property value and remove after confirmation
Get-ItemProperty -Path "HKLM:SOFTWARE\WOW6432Node\Savance\EIOBoard Application" -Name "WebAddress"
Remove-ItemProperty -Path "HKLM:SOFTWARE\WOW6432Node\Savance\EIOBoard Application" -Name "WebAddress" -Confirm
