[wix-users] Installation directory must be on a local hard drive

[Schooley, Ron]

I have recently started switching some of my program install packages to use WiX (which is a fantastic product, by the way). Just out of curiosity, I decided to see if the install packages being built could run under an ancient operating system version like Windows 2000 (5.0.2195). While running the install, I got the "Installation directory must be on a local hard drive" error message. I am using the WixUI_installDir WiXUIExtension from WiX 3.11.0.1507.

Although I understand very few if any people are still running Windows 2000, I was a little surprised by this failure. I can work around this issue by using the well-documented quiet (non-GUI) install option or by setting the WIXUI_DONTVALIDATEPATH Property. Given how simple the path validation code seems to be while briefly skimming it over (and as a matter of simple principle), it seems like this issue should be able to be eliminated.

Please find below a snippet of the trace log. Is it simply the case that the custom action is not getting run for some reason? Why would this be the case?
