So you upgraded to Windows 7 and your VMWare VSphere client isn’t working anymore….No problem…This is an easy fix. Just download the following file: System.dll . Then just create the following folder: c:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\lib .Now copy the System.dll file into the lib directory. Now you need to open up the following file in notepad: c:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe.config and add the following lines to it after the </appSettings>:
From the Windows 7 ‘System Properties’ click the ‘Advanced’ tab and then the ‘Environment Variables’ button as we want to add a new ‘System’ variable.
c:\Program Files\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib
That’s it. You can now run VMware VSphere client in Windows 7.
