I get the following error message (from the event log) when attempting to install GalaSoft.MvvmLight.4.1.24.0.msi:

Product: MVVM Light Toolkit -- Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: PostSetupActionVS10Machine, location: D:\, command: C:\Users\MYUSERNAME\AppData\Roaming\MvvmLight\ModifyRegistryKey.exe -i10m "C:\Program Files (x86)\Laurent Bugnion (GalaSoft)\Mvvm Light Toolkit\Snippets\CSharp\

A similar error has been reported before (see https://mvvmlight.codeplex.com/discussions/274919). Does this installation package need to be updated (as mentioned in the referenced post) or is there a work around solution?

Thanks,

Ian
