    Problems after installation with licensing or keyingedit

    Windows - License Retrieval Erroredit

    In some cases starting TouchDesigner will fail with a dialog titled TouchDesigner Key Retrieval Error or License Retrieval Error. The content of the error message will look similar to this:

    License Retrieval Error License Retrieval Error

    This can be resolved by rebuilding the wmi repository.

    Please be advised though that deleting and rebuilding the repository can cause damage to the system or to installed applications.

    To perform a rebuild of the WMI repository, please do the following:

    1. Disable and stop the winmgmt service
    2. Locate C:\Windows\System32\wbem and copy the wbem to another location for a backup.
    3. Rename C:\Windows\System32\wbem\repository folder (Note: it will not let you rename the folder if winmngmt service is still running)
    4. Enable and start the winmgmt service
    5. Open Command Prompt as Administrator, run the following commands:

    cd C:\Windows\System32\wbem\ for /f %s in ('dir /b *.mof') do mofcomp %s

    In your admin account, open Terminal and paste in the command:

    ls -l -d "/Library/Application Support/ca.derivative"

    You should get a line back like so. Note that the group owner should be admin, not wheel:

    drwxrwxr-x@ 10 root admin 340 17 Jan 2017 /Library/Application Support/ca.derivative

    If you are missing the directory, then enter this command in the Terminal:

    sudo mkdir "/Library/Application Support/ca.derivative"

    If you do not have matching permissions (1st column), then enter this command in the Terminal:

    sudo chmod 775 "/Library/Application Support/ca.derivative"

    If you have wheel instead of admin as group owner (4th column), then enter this command in the Terminal:

    sudo chgrp -R admin "/Library/Application Support/ca.derivative"

    Restart TouchDesigner and try installing or disabling the key again.

    Firewall Issuesedit

    If the Key Manager is giving connection errors, it may be due to a firewall blocking access to our key server. Ensure TCP connections to both www.derivative.ca and derivative.ca on port 443 is allowed through your firewall.

    Proxy Serveredit

    TouchDesigner currently does not make use of proxy server configurations that your system may be using. You'll need to use the Offline key generation method if your connection requires a proxy server.

    Problems during Uninstalledit

    Installer exits during Uninstall without erroredit

    When this happen, best practice has been to restart the computer to free up any possible locks on the folder. Most commonly after a restart the remaining files will have been removed and a fresh install can be started.
