Oh, thank you for this interesting idea!
But I think writing a little bootstrap .bat file is much less effort for my
scenario.

Betreff: Re: [WiX-users] environment variable available in executed program
hi,
have a look at the msdn-documentation for the Environment Table [1]:
Note that environment variables do not change for the installation in progress
when either the WriteEnvironmentStrings action or RemoveEnvironmentStrings
action are run. On Windows NT and Windows 2000, this information is stored in
the registry and a message notifies the system of changes when the installation
completes. A new process, or another process that checks for these messages,
uses the new environment variables. On Windows 95 and Windows 98, this
information is stored in the Autoexec.bat file, and do not affect the system
until a system reboot.
you probably have a chance by sending a WM_SETTINGCHANGE (see [2]) via a custom
action (after WriteEnvironmentStrings and RemoveEnvironmentStrings action). but
i have not tried that and it may not work...

I had a similar thing with a new env var not being found by the program I was
launching. I can only conclude the following:
When you launch your MSI, it's value for PATH does not include your new folder.
The changes get committed to the system, but your MSI still has it's original
set of env vars. Since your batch file is run from the MSI, it has the same
env vars, and so doesn't have the updated path.

Hi,
1) I'm adding my newly installed dir to the system path Environment
Id='env_entry' Name='PATH' Action='set' System='yes'
Part='last' Permanent='no' Value='[INSTALLDIR]share\bin' /
2) scheduled CA runs a .bat file that uses an executable from the
share\bin dir added to path.
CustomAction Id='LaunchFile' FileKey='test.bat'
ExeCommand='-d [INSTALLDIR] ' Return='asyncNoWait' /

3) In the up-popping console window I can see that the executable was
not found. But after opening a new cmd-session, it is available. Why
is that not in the console wix opens for me? How do I achieve this?
Thank you very much,
Thomas
