The ICE warnings are trying to help you author a correct MSI package but it
doesn't know the details of how the application works so the warnings
should be ignored intentionally because you've analyzed them and decided
they do not apply in your situation. The WiX linker is reporting the ICE
warnings as errors likely because you told it to treat all warnings as
Why should the installer create this directory if the application should
create this folder? The installer can only create that per-user directory
for the user that runs the installer. If the application is every run by
any other user, then the directory will not exist anyway and the
application will need to create it itself if the application wants to write
a file to that directory.
If the installer should create the per-user directory, then the ICE warning
is telling you that the per-user component cannot use a file (directory in
this case) as the key path but instead it should use a registry key under
HKCU as the key path. The key path is used as one bit to determine whether
a component is installed or not by the Windows Installer Engine.
The other ICE warning suggests you should add the directory to the
RemoveFile table so that it gets removed at uninstall time *but* the
per-user directory for the user uninstalling the MSI will be deleted so you
could still leave behind configuration data behind if other users run the
Should this configuration file really exist on a per-user basis? If yes,
then you'll likely need to leave them behind at uninstall anyway. And since
the application will need to create the directory if it doesn't exist, then
it should just be responsible for creating the directory instead of the
