The old installer was an Visual Studio Installation Project. The Old Version Number was 5.015.004 with an Different guid. So the wix installer is Doing a Major Upgrade.
During the installation of the new Version the uninstallation of the Old Version is scheduled. During the uninstallation an error occured. The error Message is the missing CustomAction.dll because the dll is searched within the wrong path. The new wix installer does Not Need this CustomAction.dll so it is Not Part of new Version. I Hope i was able to clarify the Problem. Mit freundlichen Grüßen i. A.

If the Dll is called InstallUtilLib.dll than that's the Visual Studio Dll. I was pointing out that managed code custom actions in VS 2010 are shimmed with a VS C++ Dll, but it's not clear if you were previously using WiX or VS setup projects to build your MSI files, because otherwise the references to VS 2010 and 2012 aren't really relevant. So you've got an error during an upgrade (which includes an uninstall of the older product) and you have a custom action that can't find a Dll. If you could clarify the details it might help. --------------- Phil Wilson On Tue, Apr 15, 2014 at 1:01 PM, Michael Turner <mcturner...@gmail.com<mailto:mcturner...@gmail.com>> wrote: Chris, Is your new version a "Major Upgrade" (http://msdn.microsoft.com/en-US/library/aa369786.aspx), as opposed to a "Small Update" or "Minor Upgrade" (http://msdn.microsoft.com/en-us/library/aa370579.aspx)? Also, if it is a Major Upgrade, then when is your RemoveExistingProducts action scheduled? (http://msdn.microsoft.com/en-us/library/aa371197.aspx; http://wixtoolset.org/documentation/manual/v3/xsd/wix/majorupgrade.html) Could you also please provide XML snippets of the custom action in the source code for the *previous* version of the installer? What I'm looking for is both the CustomAction element that describes what the custom action does, as well as all *Sequence/Custom and/or UI/Publish element(s) that schedule the action and specify the conditions under which it should run. Regards, Mike Arthur, Christopher wrote Thx for the answer. The uninstallation of the previous Version is working fine. The error is ocuring only during Upgrade within the wix installer. The strange thing the CustomAction.dll is searched within the default targetdir of the wix installer and Not within the targetdir of the already installed Application. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Strange-Beahaviour-while-installing-previous-Version-tp7594117p7594142.html Sent from the wix-users mailing list archive at Nabble.com<http://Nabble.com>. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
