I see why you need a custom action. Your best approach is to have your custom action write temporary rows to the RemoveFile table and let Windows Installer do the deleting for you. That would prevent some potential problems.
The pattern for these types of CAs is described in Bob's well-thumbed blog page at http://www.joyofsetup.com/2007/07/01/semi-custom-actions/ -----Original Message----- From: MeCoco [mailto:vcotirl...@hotmail.com] Sent: 29 November 2010 14:25 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] QtExecDeferred and using a property in the cmd line Hi Peter. Thx for your answer, but I can't do that because I need the files to be removed _only_ when uninstall (not updates) and I have <RemoveExistingProducts After="InstallInitialize"/>. And as I described here: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/BUG-limita tion-in-WIX-MSI-No-way-to-distinguish-between-an-uninstall-and-an-update -when-lt-RemoveExi-td5776494.html when REP is after InstallInitialize, it can't be done with Component conditions. So I need a CustomAction which deletes the file and can be conditioned to happen only when real uninstalls. Because of that I got to the code below, which doesn't work. Can somebody pls help me?
