Hi John, I'm doing it this way as of now ..
<InstallExecuteSequence> <Custom Action="RunInstallScript" After="InstallFiles" >NOT Installed</Custom> </InstallExecuteSequence> <InstallExecuteSequence> <Custom Action='BeforeUninstall' Before='InstallValidate'>Installed AND (NOT REINSTALL)</Custom> </InstallExecuteSequence> <CustomAction Id="RunInstallScript" ExeCommand="cmd /c install-solidfireprovider.cmd" Directory="INSTALLFOLDER" Execute="deferred" Return="check"/> <CustomAction Id="BeforeUninstall" ExeCommand="cmd /c uninstall-solidfireprovider.cmd" Directory="INSTALLFOLDER" Execute="immediate" Return="check"/> The only problem is repair doesnt execute the uninstall script, so the filesinUse pops up during repair. Otherwise, I dont see it during uninstall because I guess my uninstall CA gets called before Install Validate, which is what I want. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/stop-a-service-before-uninstall-tp7588564p7588570.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
