To use any of the WiX extensions you need to do two things. 1) Add the schema statement as you originally had.
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension" xmlns:netfx="http://schemas.microsoft.com/wix/NetFxExtension" xmlns:bal="http://schemas.microsoft.com/wix/WixBalExtension" > The above three UtilExtension, NetFxExtension, and WixBalExtension are all correct and necessary, but not enough. If you then add any code to your project related to these three extensions like: <BootstrapperApplicationRef Id="ManagedBootstrapperApplicationHost"> ... You will get the errors which you observed. 2) You also need to 'Add a Reference' to your Project file. For me on VS2010 (and I think it is similar on 2012) look at you Solution tree. There is a virtual folder named "Reference". Right-Click and select Add. You will get a dialog that has tabs Project, Browse, and Recent (at least on 2VS2010). In Browse point at you Wix installation folder, typically C:\Program Files (x86)\WiX Toolset v3.8\bin and select the DLL which is named and related to the Wix extension that you are trying to use, in this case WixBalExtension.dll. If you are also trying to use the UtilExtension or the NetFxExtension, you need to repeat this process for each DLL. (If you ever move the Wix Toolset to a different path, like E:\ then you will need to go to each project and fix these references.) If you still have problems you can enable more verbose build logs in VS Tools\Options\Projects and Solutions\Build and Run. Actual relevant sections of code (and if necessary a detailed build log) will clarify what the problem is. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Visual-Studio-2012-Does-the-Wix-installer-need-a-connection-to-the-Internet-to-create-an-installatio-tp7591955p7592043.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
