We let the user modify the target directory in our UI, but I find I need to use a type 35 Custom Action (no external code involved, though) to alter the property being used. Also, on an upgrade we present the user with the same directory they chose the first time around, but they can alter it to do the major install someplace else if they want to. (i.e. their C: drive where they first put it is getting full, so they want to "upgrade" to E:)
<Property Id="HARLANDFSFOLDER"> <RegistrySearch Id="HFSRootSearch" Root="HKLM" Key="Software\HarlandFS\E3" Name="InstallDirectory" Type="directory"/> </Property> <CustomAction Id="SetHarlandFSFolder" Directory="HARLANDFSROOT" Value="[HARLANDFSFOLDER]"/> And then in the InstallUISequence <Custom Action="SetHarlandFSFolder" After="CostFinalize"><![CDATA[HARLANDFSFOLDER <> "" ]]></Custom> -----Original Message----- From: Nicholas Makin [mailto:nma...@opentext.com] Sent: Thursday, September 03, 2009 10:12 AM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Allowing the user to override the install directory Please excuse my frustration but I am finding WiX to be neigh worthless - why? Because there is a plethora of information by half of it is no good and the other half points you to the mysterious MSI documentation which is wonderful if one could figure out how that translates to WiX. All I want to do is have a default directory structure: <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder" Name="PFiles"> <Directory Id="INSTALLDIR" Name="Acme"> <Component Id="AppSettings" Guid=" xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx "> But let the user choose to install in another place: <Property Id="WIXUI_INSTALLDIR" Value=" INSTALLDIR " /> <Publish Dialog="InstallDirDlg" Control="Next" Event="SetTargetPath" Value="[WIXUI_INSTALLDIR]" Order="1">1</Publish> <Publish Dialog="InstallDirDlg" Control="Next" Event="NewDialog" Value="VerifyReadyDlg" Order="2">1</Publish> <Publish Dialog="InstallDirDlg" Control="ChangeFolder" Property="_BrowseProperty" Value="[WIXUI_INSTALLDIR]" Order="1">1</Publish> <Publish Dialog="InstallDirDlg" Control="ChangeFolder" Event="SpawnDialog" Value="BrowseDlg" Order="2">1</Publish> However when I use the above - no matter what the user chooses the component is always placed at: C:\Program Files\Acme - i.e. the dialog is pointless. So I made this change: <Property Id="INSTALLDIR" Value="Acme" /> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder" Name="PFiles"> <Directory Id="INSTALLDIR" Name="."> <Directory Id="FILELOC" Name="OTInstaller"> <Component Id="AppSettings" Guid=" xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx "> Well this tries to install to come network drive named Acme. I did find that I can insert "C:\Program Files\Acme" but this results in a warning about hard coding directories This is what I guess I will have to live with. I did try something like [ProgramFilesFolder]\Acme - but this too resulted in an error - I guess a property can't be used to set another property in this way. Ultimately I know that my frustrations are a result of just not understanding how MSI works with directories but all I have are 100's of examples to extrapolate from and none of them seem to offer correct advice (i.e. it either does not work (WiX Wiki example) or results in errors). As I fight my way though building this installer I find that this has consistently been the case - 100's of examples but no real information to help you extrapolate to achieve what you need which is often just a tiny tweak on the example. Without some sort of understanding there is no way to get form the example to the desired functionality - and how can you build understanding from examples that don't work? So aside from helping me get these files placed where the user wants them - if someone ever figure out the secret to WiX - write a good solid book on it and I will buy it and I know other users will love to have it. WiX is wonderful - but so much time gets wasted trying to work out details. I am ever to tempted to use VBScript to do custom actions to do things that WiX clearly can do - just because I cannot figure out HOW to do it. This is madness (I have found many books with WiX examples - generally a 2-3 page section with an example that is usually copied from the tutorial (or darn near) or the Wiki.)
