I am creating a Wix 3.0 installer for a product and have come against a number of issues (migrating from InstallShield). I had a general look around but cant find the answers so im hoping someone can help me: 1) The doc tells me that I should have one component per file and I want to have all installation files in a single feature but then I get a warning (LGHT1076 : ICE47) that I should try and have fewer than 817 components in a feature. Why is this a bad idea? 2) I wish to create a folder structure in the start menu using the following folder structure on installation and use the statements below to do it: ProgramMenuFolder\Vendor\ApplicationName ProgramMenuFolder\Vendor\ApplicationName\Advanced <Directory Id="ProgramMenuFolder" Name="Programs"> <Directory Id="StartMenuVendor" Name="VendorName"> <Directory Id="StartMenuAppName" Name="AppName"> <Component Id="StartMenuEntries" Guid="..."> <CreateFolder Directory="StartMenuXanalys" /> <RemoveFolder Id='StartMenuAppName' On='uninstall' /> <RemoveFolder Id='StartMenuAppAdvanced' On='uninstall'/> <RemoveFolder Id='StartMenuVendor' On='uninstall' Directory='StartMenuVendor'/> <RegistryValue Root='HKCU' Key='Software\[Manufacturer]\[ProductName]' Type='string' Value='' KeyPath='yes' /> </Component> <Directory Id=" StartMenuAppAdvanced" Name="Advanced"> <Component Id=" StartMenuAppAdvanced" Guid="..." > <CreateFolder/> <RemoveFolder Id= StartMenuAppAdvanced On='uninstall'/> </Component> </Directory> <Directory Id="StartMenuAppAdvanced" Name="Advanced" /> </Directory> </Directory> </Directory> I find that the VendorName folder is not created on install and I get a compile error for the Advanced folder (presumably because it has no file elements?). Can someone tell me why the former error occurs and is there a way to force creation of a (potentially empty) folder. 3) Third issue is related to COM server registration. I have a out of process COM server implemented in a exe (e.g. app.exe) file with an external type library (e.g. app.tlb). I want this to be registered during install and unregistered during uninstall (the equivalent of app.exe /RegServer and app.exe /UnRegServer). I thought I could simply do this: </Component ...> <File Id="filA7723DE8CBBF678AC3819B61A67C4CD5" KeyPath="yes" Source="app.exe"> <TypeLib Id="86B995C7-EC9C-11D4-BEEA-000347024BE1" Description="Application Object Library" Language="0" MajorVersion="1" MinorVersion="0" /> </File> </Component> Where the typelib line is extracted by harvesting the entries of app.tlb using heat (and just taking the first line). This doesnt seem to work. Thanks sanjay ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
