Thanks for your comments. It looks like I cannot find the value "2CF25F13-12F8-4B54-AC62-0F29F54E4F54" in my .wxs file. I am guessing it is a mistake to leave the <Product Id="*" > as an asterisk? (I inherited this file from a previous developer and am still very new to WiX.)
"Is the GUID in the log the same as the product code of the MSI you are trying to install? (IE, is the MSI already installed on his machine?)" [David] He had a previous version of the product installed on his machine. I believe he installed it while he was using his original windows user. He is now trying to upgrade the product using his new windows user. He saw the error when we were just trying to upgrade the package. He then uninstalled the older version and tried to run the 6.4 installer again with the same error. "If so, you may need to recache the package, then do an uninstall." [David] What are the steps to recache a package? I will certainly lookup the steps on my own as well. "Is this MSI a pre-user install" [David] Do you mean 'per-user' install? If so, then yes we install all of the components to a directory within "LocalAppDataFolder". However, I am wondering if this warning that appears when I build the installer may be affecting it as a true 'per-user' install. For example, "error LGHT0204 : ICE38: Component TRADOS_PLUGINS installs to user profile. It must use a registry key under HKCU as its KeyPath, not a file." Here is some of the XML from the .wxs file: <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="LocalAppDataFolder"> <Directory Id="SDL" Name="SDL"> <Directory Id="SDLTradosStudio" Name="SDL Trados Studio"> <Directory Id="Ver11" Name="11"> <Directory Id="Plugins" Name="Plugins"> <Directory Id="APPLICATIONROOTDIRECTORY" Name="Packages" /> </Directory> </Directory> </Directory> </Directory> </Directory> </Directory> <DirectoryRef Id="APPLICATIONROOTDIRECTORY"> <Component Id="TRADOS_PLUGINS" Guid="f80ba0d3-4385-4a11-a79f-682a715e8eed" KeyPath="yes"> <File Id="Lds.Psd.Lp.Trados.ScriptureTranslator.sdlplugin" Source="LDSScriptureTranslator\Version 5\Signed\Lds.Psd.Lp.Trados.ScriptureTranslator.sdlplugin" /> ... </Component> </DirectoryRef> -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/SOURCEMGMT-Failed-to-resolve-source-MainEngineThread-is-returning-1612-tp7598095p7598108.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
