We just tried installing our product under Windows 10 Technical Preview and are getting an error: MDAC 2.5 Sp3 cannot be installed on this machine. MDAC 2.5 Sp3 requires any one of the following configurations: Microsoft Windows 95 with Internet Explorer 3.02 or later Microsoft Windows 98 with Internet Explorer 3.02 or later Microsoft NT® 4 with Internet Explorer 3.02 or later Setup will exit now. Please restart the Setup after installing the necessary updates to this machine. The install works fine on released versions of Windows including 8/8.1 and MDAC 6.3.9600 seems to be installed on the target machine. We could update the installs to use the MDAC 2.8 merge module (we still need to be able to install on Windows XP). Is this a solution? Does MDAC really need to be installed anymore or is it already automatically installed on Windows? Thanks, Ed

I set the files in their own special directory, then used MsiSetTargetPath to set the directory to the desired application directory. The files now install to the correct directory and automagically uninstall without me having to do anything. 🙂 The only question left now is how to keep the files from installing to their default directory (under INSTALLDIR) if the other application is not installed at all?

I have a set of files that need to be installed in another application's installation directory if that other application is installed. I can detect if that application is installed but I'm not sure how best to direct those files to the other application's installation directory. I'm using InstallScript now in the Feature_Installing function to detect the other application by reading the system registry and that is working well. Thanks.

We've got an InstallScript install using IS 2008 and lately one of the Windows 7 machines we've been installing on is getting an Feature Transfer Error (Error: -1925). The other part of the problem is that the program is left partially installed but cannot be uninstalled via Control Panel. The two questions I have are: 1. What is causing the error and can the issue be resolved? 2. Can I catch the error and force the install to roll back changes to the computer? Thanks, Ed

I found the answer! The function to call is MsiGetFeatureState. My code now looks something like this: NUMBER nInstalled, nAction; BOOL bFeatureInstalled; //... if (MsiGetFeatureState(IMSI_HANDLE, "FeatureName", nInstalled, nAction) = ERROR_SUCCESS) then if (nInstalled = INSTALLSTATE_LOCAL) then bFeatureInstalled = TRUE; else bFeatureInstalled = FALSE; endif; else //... endif;

I'm trying to determine which features are already installed during a Modify install. I've tried using FeatureIsItemSelected, but I'm not sure what to pass in for the szFeatureSource parameter. I've tried MEDIA, but that seems to return TRUE regardless. Is this the right function to call? What should I be using for szFeatureSource? Thanks, -Ed
