Hi everybody, I have to make 2 different installation one following the other. The installation order is important, the second have to come after the first. First installation is a BasicMSI built as non compressed release. Second installation is an InstallscriptMSI built as a single exe. The schema is: when the first is finished, clicking "OK" on the "SetupCompleteSuccess" mask I launch an installscript function that launches the second installer. I use LaunchAppAndWait(szMyFullPathExe, "", NOWAIT); in the installscript function. This works fine on XP, SEVEN, VISTA but not on Win8.1 I have tried also with LaunchApplication but the result is the same. It always return a code -1. And do nothing. Also launching a little .NET executable that launches the installer ... nothing. Same (bad :mad:) result making a custom action in the Execute sequence ( placed after installfinalize) that launches the script function. Has Win8 some security stuff that deny to an installer to launch a second installation ? Note: 1) I have two different test pc; no AV sw installed. Just Windows Defender disabled. UAC set the lowest level. 2) I need to execute some code before launch the second installation, so I need to execute it from an installscript function. Thanks in advance. ... View more

Hello everybody, Issue: I have an error during a major update. Introduction: I use the major Scenario: I have an error on my installation (installscript MSI project ) with custom action and installscript function so I have prepared a very simple Installscript MSI project with just a feature and a file installed. I have tested the installation and uninstallation of the simple project: it works fine. I have installed the 1.0.0 version and after I have prepared the 1.1.0 version. To fire the major update I have also changed the product code. I have shaped the update in the upgrade section as: I leave the default configuration on a major update to uninstall the old version and after install. When I launch the setup, after clicking the Install button at the end of the installation masks, when it should start the unistallation of the old version I get this error: and this is the message: Problem signature: Problem Event Name: APPCRASH Application Name: setup.exe_TestInstallScriptMSI Application Version: 2.1.7.0 Application Timestamp: 53723d9e Fault Module Name: ISSetup.dll Fault Module Version: 21.0.0.289 Fault Module Timestamp: 5372280b Exception Code: c0000005 Exception Offset: 0002e9f0 OS Version: 6.1.7601.2.1.0.272.7 Locale ID: 1040 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 Closing the error the installation goes on and finalize good. As result I have the new version installed but the old one is still shown in the Installed Application with out the icon. Trying to uninstall it does not work throwing a message: "1628: Failed to complete the installation", leaving the item in the Installed application form. Trying to uninstall the 1.1.0 version it works properly. Which is the error ? I found in this page that major version are managed by msi and installscript msi. That's why I've choosen it. Thanks in advance for the help. ... View more
