InstallShield 10:52:44: Invoking script function DeleteInstallDir InstallShield 10:52:44: Registering Msi Server. Maybe it helps anyone: MSI (s) (80!84) : Creating MSIHANDLE (77) of type 790531 for thread 3716 Whereas I couldn't find any properties that might be passed manually through msiexec, here's the part where the installer creates the 'Delete Folder?'-dialog along with the function that is called if the user presses yes. exe ?Īs suggested (thank you!), I turned up msiexec's logging level during uninstallation. Is there any way to provide an unattend.xml for this installer or does anyone know about a specific command switch I could use with Lenovo's System Update installer. Therefore, when uninstallation is started silently, the installer will hang indefinitely since there's no way for the user to interact with the installer. However, the Lenovo installer asks the user if they want to delete the program folder after uninstallation, which requires user input (yes or no). Usually, one could do that by using TVSU's UninstallString with the /quiet or /qn parameter: MsiExec.exe /X /qn I want this update to supersede all lower versions and for that I need to uninstall those previous version silently. Need to rollout the newest Lenovo ThinkVantage System Update (v) via SCCM 2012.
