It won't uninstall. Just detects then allows you to put a message up and advise the user to uninstall the old per-user app then re-run setup.
I think you are correct that user needs to be admin to run this. -----Original Message----- From: Rob Mensching [mailto:[EMAIL PROTECTED] Sent: Friday, October 24, 2008 10:44 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] uninstall per user product Only when admin right? And this won't uninstall right? I think you'd need to load all the user's profiles to uninstall per-user applications. Loading user profiles is tricky from what I've heard. -----Original Message----- From: Ian Elliott (Excell Data Corporation) [mailto:[EMAIL PROTECTED] Sent: Friday, October 24, 2008 10:41 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] uninstall per user product I've used a custom action to do something similar in the past. A stripped down version of the code is below. I can't guarantee 100% effectiveness but it worked for my needs at the time. UINT __stdcall FunctionName (MSIHANDLE hMsi) { UINT uiStatus = ERROR_SUCCESS; WriteToLog( hMsi, _T("Entering")); uiStatus = MsiEnumProductsEx( _T("{PUT_GUID_HERE}"), // product code to search for _T("s-1-1-0"), // search all users MSIINSTALLCONTEXT_USERMANAGED | MSIINSTALLCONTEXT_USERUNMANAGED | MSIINSTALLCONTEXT_MACHINE, // search all users 0, NULL, NULL, NULL, NULL); if (uiStatus == ERROR_SUCCESS) // Product was found { MSIHANDLE hError = MsiCreateRecord(1); MsiRecordSetInteger(hError, 1, 2001); // Use code 2001 from the msi's Error table. Author 2001 in wix file. MsiProcessMessage(hMsi, INSTALLMESSAGE_ERROR, hError); } else // we didn't find the Product { WriteToLog( hMsi, _T("Product not found")); } WriteToLog( hMsi, _T("Leaving")); return uiStatus; } -----Original Message----- From: Rob Mensching [mailto:[EMAIL PROTECTED] Sent: Friday, October 24, 2008 10:36 AM To: General discussion for Windows Installer XML toolset.
