Use a utility like pathman.exe to set and remove path entries, think it is part of NT resource kit

You should use Custom Actions to add Environment Variables this can be done from Setep Editor. The advantage Of Doing this is that then you can set it to only install the path or environment variable if it is not there.

Tocra is right, make sure on the replacement drop down box you choose the selection "Append at end of current value".

Hi
I known how I add the path, but how do I remove it during an uninstall? does anyone have a script example?

Haden,

I have had issues with paths not removing properly (usually deletes the entire path value) when using the Features -> Complete (or whatever feature) -> Right Click -> New -> Environment Variable. If you have any component within the feature that have a bad key association you will have problems. Make sure you don't have any "red" errors in your components list and use the following structure in the dialog box for adding an environment:

Name: PATH
Value: [ProgramFilesFolder]My Dir;
Operation: Set value on install and delete on uninstall
Replacement: Append at end - or - insert at beginning
Check the Windows NT/2000/XP system environment variable as appropriate

I also feel more comfortable adding multiple PATH environment variables rather than cramming them into one statement.

This is the proper, supported method for adding/removing environment variables in Windows Installer. You definitely don't want to use the registry to set this environment variable. Some other good examples where a custom action should come into play are the services and hosts files (in system32\drivers\etc), the HKLM\CSS\Services\EventLog\Application\sources (or any REG_MULTI_SZ value), the TNSNAMES.ORA oracle connection file, etc. IOW, any file or value that other programs use to store information should be edited rather than overwritten.

I use this method...

Add a new row to the Environment Table:

Name = *=-Path
Value = [~];ENTER_VALUE_HERE
Environment = PATH
Component = ASSIGN_COMPONENT_HERE

Always install and uninstalls properly.

Hope this Helps,

Steve

Steve's method is good. In Wise for Windows Installer 5 environment variables are on the installation expert under features. About time really, Wininstall has had it up front for years.
