You could always use the COM library if you're not comfortable with the C API calls. Add a COM reference to "Microsoft Windows Installer Object Library" to your project...
Installer.get_Features and Installer.get_FeatureState look like they might be useful. -----Original Message----- From: Anil Patel [mailto:apatel...@googlemail.com] Sent: Thursday, August 25, 2011 11:12 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Identifying Features that have been installed Hi Peter, Really appreciate your feedback on this. The MsiGetEnumsFeatues() is defined as UINT MsiEnumFeatures( __in LPCTSTR szProduct, __in DWORD iFeatureIndex, __out LPTSTR lpFeatureBuf, __out LPTSTR lpParentBuf ); So to get the product code, I found this code [DllImport("msi", CharSet = CharSet.Auto)] static extern int MsiGetProductCode(string component, StringBuilder buffer); public static string GetProductCode(string component) { StringBuilder productCodeStringBuilder = new StringBuilder(512); switch (MsiGetProductCode(component, productCodeStringBuilder)) { case ERROR_SUCCESS: return productCodeStringBuilder.ToString(); // *Please* don't actually just throw an exception like this. // Throw the relevent exception based on the error code returned. case ERROR_BAD_CONFIGURATION: throw new Exception("The configuration data is corrupt."); case ERROR_INSTALL_FAILURE: throw new Exception("The product code could not be determined."); case ERROR_INVALID_PARAMETER: throw new Exception("An invalid parameter was passed to the function."); case ERROR_UNKNOWN_COMPONENT: throw new Exception("The specified component is unknown."); default: throw new Exception(); } } The problem is thay symbolic constants in the switch statement (eg ERROR_INVALID_PARAMETER which are uints) aren't recognised so error on compile. Do you know how I can resolve these. I'm assuming there might be an Enum for them but I can't locate them. Again any help would be appreciated. Regards, Anil.
