UNC AppData(Roaming) directory cannot be accessed



What happens:

Unity.exe cannot boot in a particular environment.


When Unity.exe runs, it creates or accesses the Roaming folder like
but it cannot be accessed in some environment.

Using Active Directory and folder redirection, that Roaming folder path comes to UNC like
so that the cmd.exe (bat file) can never access it while booting Unity.exe.

This may happen mostly educational facilities.

    This issue happens in view of a change that was made in Windows 10, adaptation 1803. This change incidentally caused organizers that are typically prohibited from meandering to be synchronized by wandering client profiles when you sign on or log off.

    When I read this article, I got a few knowledge about UNC Appdata and its uses. Your article gives me new information about the application data folder, and it is very informative. Please add more details about the UNC AppData.

    I can affirm that Appdata envelope redirection is regularly utilized in instructive offices. Debilitating it is generally impossible. On the off chance that Unity doesn't work appropriately in numerous edu situations, I'm certain that numerous potential future clients are lost.

    I have a similar issue with building for visual studio with latest version. The above fixes don’t work though.. seems t o be an issue with the %appdata%\locallow.. the files get created in the folder but appears not to be read later!

    This problem seems NOT to be fixed, not even in the newest version 5.3.5f1

    When Appdata\Roaming is redirected to a UNC path, Unity cannot start properly and when the "Welcome to Unity" / "Sign into..." dialog should appear, the dialog box remains dark grey and empty insted. With a user w/o a redirected Appdata folder, Unity works fine on the same machine.

    I used the Sysinternals Process Monitor tool to confirm that Unity.exe tries to access the redirected Appdata folder w/o success.

    I can confirm that Appdata folder redirection is very often used in educational facilities. Disabling it is usually not an option. If Unity does not work properly in many edu environments, I'm sure that many potential future customers are lost.

    Also note: I ran in to this this issue with 5.3.4f1 installed so the issue seems to have regressed

    you can circumvent this issue by:

    first mapping the networked home dir to a driverletter
    (i.e. "net use k: \\fileserver\users\USER_NAME" )

    then setting
    "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\AppData" to "K:\Appdata\Roaming"

    NOTE: you need to change the registry setting, changing the %APPDATA% environment variable in a shell and then starting unity from that shell did not work
