Wix Installer Error 2343

Question

so I have been trying to develop this installer for my application. I decided to change my GUI to <UIRef Id="WixUI_InstallDir" />. According to a tutorial that I was reading I also need to include <Property Id="WIXUI_INSTALLDIR" Value="TOP_LEVEL_DIR" /> if I use that GUI. But, since I changed the GUI and added this line I am getting an error (2343). I have posted the MSI Log below as well and it is complaining about a location?

Error: MSI (c) (CC:84) [13:27:33:140]: Note: 1: 2343 DEBUG: Error 2343: Specified path is empty. The installer has encountered an unexpected error installing this package.

Answer 1

The value of <Property Id="WIXUI_INSTALLDIR" Value="TOP_LEVEL_DIR" /> is what you specify as allowing the user to set with the UI dialog box. In this case, you are identifying TOP_LEVEL_DIR as the ID of the directory that you want the user to set, but you don't have it mapped to any corresponding Directory tag.

Assuming you're trying to allow them to change the root install directory, try setting the value of WIXUI_INSTALLDIR from TOP_LEVEL_DIR to INSTALLDIR instead.
