I uninstalled SoMachine 4.x and Machine Expert 1.1, why do I keep receiving an incompatible error message when installing Vijeo Designer SP9?


When trying to install Service Pack 9 on top of Vijeo Designer an error will appear stating that there is an incompatible version of SoMachine / EcoStruxure Machine Expert installed.

Product Line:

Vijeo Designer 6.2, SoMachine 4.0, SoMachine 4.1, SoMachine 4.2, SoMachine 4.3, EcoStruxure Machine Expert 1.0, EcoStruxure Machine Expert 1.1


After uninstalling SoMachine and Machine Expert make sure to delete this registry keys if they exist:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\SoMachine Software

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\Machine Expert Installer

Then reinstall Vijeo Designer 6.2 and apply SP9 as administrator.

Note: SP9 and older is compatible with EcoStruxure Machine Expert 1.2 and up.
