This registry _value_ (not key) should almost certainly be created by the hardware INF, not by your application installer. USB devices will normally have a serial number which is part of the registry key name; if it doesn't have a serial number then Windows will create a unique key based on the port that the device is plugged into. This means that your DeviceHandlers value won't be applied correctly to a device if the user moves it to a different port.
If you are using serial numbers but each device has the same serial number, you have a different problem - if a user plugs two of the devices into the same computer, Windows may behave oddly. See Raymond Chen's blog at http://blogs.msdn.com/oldnewthing/archive/2004/11/10/255047.aspx. Your Windows Installer-based package should not be creating this value, in my opinion. At least, if I'm reading http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc /platform/shell/programmersguide/shell_basics/shell_basics_extending/aut oplay/autoplay2k_cookbook.asp correctly. -- Mike Dimmick -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of BrianG Sent: 27 September 2006 14:39 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Prevent Registry Removal My company has different applications that use the same USB device. As such, they all install registry keys for the AutoPlay functionality of the device. I need to prevent the removal of the device's DeviceHandlers key upon uninstall of an application. If this key is removed, it breaks the AutoPlay for all the other apps that use the device. If I suppress the entire RemoveRegistry function then the uninstalled app appears in the AutoPlay list but will, of course, not launch. Does WIX have anything that would allow me to prevent the removal of this single registry key or possibly re-write the key at the end of the uninstall process?
