Receiving an “Unhandled Registry Error (CFO)” after upgrading from Windows 7 to Windows 10.
Several users who upgraded to Windows 10 and didn’t do a fresh EccoPro installation received an “Unhandled Registry Error (CFO)”:
The “Unhandled Registry Error (CFO)” is a Registry permission problem. It has to do with Windows updates or upgrades which changes Registry permissions.
If you attempt a reinstallation of EccoPro the regular Windows uninstaller doesn’t do a thorough enough job to eliminate old registry entries and therefore you will receive Registry Errors.
As with other programs, a regular Windows uninstallation did not remove “Registry” remnants of a prior installation. Uninstall EccoPro from the control panel and run “regedit” from the command prompt. Make sure everything under HKEY_CURRENT_USER ->Software -> NETMANAGE -> Ecco is removed before you attempt a new EccoPro installation.
Make sure your operating system is 64-bit. Close every open program including the Virus Scanner and try to use the 64-bit Installer EccoProX version 184.108.40.206 (right-click and run the “EccoProX64 – Installation.msi” as Administrator in C:\EccoPro64) and see if you get EccoPro running and the Unhandled Registry error disappears.
