path - Can anyone give me a example of modifying windows environment system variables in WIX?

Question

I still don't know how to add the installdir into the PATH of the Windows System Variables after I went through the WIX tutorial.

I tried to use

  Environment Id='UpdatePath' Action='create' Name='PATH'  System='yes' Value='[INSTALLDIR]' 

But there was no change in the Path after I installed the program. I can hardly find sample code of WIX anywhere. Please help me, thanks a lot!

Answer 1

You should be able to use:

<Environment Id="PATH" Name="PATH" Value="[INSTALLDIR]" Permanent="yes" Part="last" Action="set" System="yes" />

This should add a new entry to the environment path, set to [INSTALLDIR].
