It would appear that the preview handler you are using does some calculations to determine what changes to make to the box (a part of the evil of self-registration is when there is no way to know beforehand what some component will try to do to your box).
You will need to get a hold of the source code to your preview handler and see what it is doing, and try to distill out of that what really needs to be done in a declarative way. -----Original Message----- From: Daniel Moody [mailto:dani...@gibbscam.com] Sent: Thursday, July 15, 2010 9:23 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Difficulties registering a Preview Pane handler Hello, I'm trying to register a Preview Pane handler for our product's files using Wix. Unfortunately, Heat is unable to harvest anything from the preview handler .dll file. Iit gives a HEAT5151 error and reports "Exception has been thrown by the target of an invocation." I've tried using the before-and-after registry snapshot approach, which has given me a large number of registry keys and values, which oddly work fine on most computers but not at all on a few. My installer is "GACing" the .dll just fine, and if I run regasm from a command line after my installer is finished, everything works as expected. As I've just had the installer project transferred to me recently, I often reference our old InstallShield installer to see what my predecessor did, but in this case he used a binary custom action to manually run regasm, something that I intend to avoid at all costs.
