<runtime>
<developmentMode developerInstallation="true"/>
</runtime>

Than make a bat file - and write there SET DEVPATH=%ProgramFiles%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib
%ProgramFiles%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe

SET DEVPATH=C:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib
"C:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe"

Thanks.

My Modification is to open Computer Properties

Advanced System Settings

Environment Variables

New in System Variables

DEVPATH =C:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib

Edit the VpxClient.exe.config adding

<runtime>
<developmentMode developerInstallation="true"/>
</runtime>

right before </configuration>

Copy VpxClient.exe.config to C:\Program Files\VMware\Infrastructure\VIUpdate 4.0 and rename it to VIUApp.exe.config

Notes:

Filenames of the config files appear to be case sensitive.

Theoreticly all exe's that VMWARE uses here can utilize the same trick
