Thanks for the advice Rob. I've got the directory browsing dialog in place, but I'm having issues getting my dll to work.
When I hit the Next button in my dialog, I get an 'installer information' message window that says "There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run." My dll is mostly a duplicate of the sample custom action example in the tutorial (http://www.tramontana.co.hu/wix/lesson3.php ) #include "stdafx.h" #include <windows.h> #include <msi.h> #include <msiquery.h> #pragma comment(linker, "/EXPORT:[EMAIL PROTECTED]") #pragma comment(lib, "msi.lib") extern "C" UINT __stdcall CheckLicenseFiles (MSIHANDLE hInstall) { char Pid[MAX_PATH]; DWORD PidLen = MAX_PATH; MsiGetProperty (hInstall, "MYFOLDER", Pid, &PidLen); MsiSetProperty (hInstall, "LicenseFilesFound", "true"); return ERROR_SUCCESS; } // CheckLicenseFiles I have a property MYFOLDER defined, as well as LicenseFilesFound <Property Id='MYFOLDER' Value='c:\'/> <Property Id="LicenseFilesFound" Value='false' /> Here's snippet from my dialog: <Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="Next"> <Publish Event="DoAction" Value="CheckForLicenseFiles">1</Publish> <Publish Event="SpawnDialog" Value="InvalidDirDlg">LicenseFilesFound = "false"</Publish> <Publish Event="NewDialog" Value="SetupTypeDlg">LicenseFilesFound = "true"</Publish> </Control> I have noticed that in Visual Studio the source platform for the dll is "Win32" as opposed to .NET. Could that be an issue? I'm entirely unexperienced with the .NET platform.

As I understand it, you want the user to browse to a directory where getyour existing files are, and then you want to verify them. The attached include files are put together from a couple of our products, and have had the usual secret stuff sanitised. So they might not work as-is, but will at least give you an idea of what you're looking for. In GetExistingFilesDlg the user is prompted for a path. This value will be stored in the property MYFOLDER. When they click next, this will call a custom action called checkFiles. This will have to be a DLL custom action which you need to write. It will need to get the MYFOLDER property, look for the files, and then write back a property called FILES_EXIST with "yes" if they exist, and something else if they don't. You need to set [EMAIL PROTECTED] to 'check' or 'ignore' because you need the action to finish before the installer continues. The other actions attached to the 'Next' button are based on the value of FILES_EXIST which you've just written. The installation will either continue, or the user will get a pop-up dialog. This is FilesAbsentDlg. The user is told the files are not there, and clicks OK to go back to GetExistingFilesDlg. The mailing list appears to be banning zip files, so I've renamed the extension to .piz Rob P.S. I've not attached the binary files for the background images.
