Original install of 3D Experience maker would not start and I could not get it to respond! Uninstalled and may have missed something!

Created new account and launched install, The install proceeded to Hot fix 2.7 and errored. Message Is:

Failed to get msi version for UpgradeCode [{B54313C8-7B46-297F-3AC1-85D9EFD5ECB7}].

Technical details:

The product is unadvertised or uninstalled

Error code: 1605

Unknown key HKEY_CLASSES_ROOT\Installer\Products\BE85C2B02A76B522062B1D99E055DD33

Action CheckInstalledMsiVersionAction from feature CODE\win_b64\SWXDesktopInsPreqWPT failed.

Action ID: SWXDesktopInsWPTInstalledAction

Tried many things from SolidWorks 3DEperience troubleshooting pages with no luck. Could NOT even UNINSTALL the hung NEW installation!

Anyone with advice?
