Installing Multiple Builds at Onceedit

Sometimes you will want multiple builds of TouchDesigner or TouchPlayer installed at the same time. You may need older builds to test previous projects, or you may want to try out the latest features in Experimental while keeping Official installed for your current project.


When the installer detects TouchDesigner is already installed on the system, it will give you some options for managing multiple builds

Install Parallel Build

This option will install the new build alongside whatever is already installed, without removing your current TouchDesigner builds. You can also use the new 'custom tag' feature under Custom Install and TouchPlayer options on the next page to more easily identify it, for example a tag name like Official, Experimental, or ProjectName.


Replace currently installed build

This option will replace the build you currently have installed with the new build. If you already have multiple builds installed, a list will be presented letting you pick exactly which build you would like to replace.

  • Just drag the application to any convenient location. If it conflicts with another TouchDesigner build already there, select "Keep Both" from the pop-up dialog. To keep it more organized, you can rename the application file to include the build number.
  • Right-clicking on any TouchDesigner file and selecting 'Open With >' will show a list of all TouchDesigner builds on the computer, just select the one you wish to use.

Useful Installer Command-line switches on Windows based Systemsedit

The Installer can be used with a variety of command-line switches:

  • /SILENT, /VERYSILENTInstructs Setup to be silent or very silent. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. When a setup is very silent this installation progress window is not displayed. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with DisableStartupPrompt or the '/SP-' command line).
  • /DIR="x:\dirname"Overrides the default directory name displayed on the Select Destination Location wizard page. A fully qualified pathname must be specified. May include an "expand:" prefix which instructs Setup to expand any constants in the name. For example: '/DIR=expand:{autopf}\My Program'.
  • /LOG="filename"Causes Setup to create a log file in the user's TEMP directory detailing file installation and [Run] actions taken during the installation process. This can be a helpful debugging aid. For example, if you suspect a file isn't being replaced when you believe it should be (or vice versa), the log file will tell you if the file was really skipped, and why. The log file is created with a unique name based on the current date. (It will not overwrite or append to existing files.) The information contained in the log file is technical in nature and therefore not intended to be understandable by end users. Nor is it designed to be machine-parsable; the format of the file is subject to change without notice.
  • /ExtractWill extract all relevant files from the installation into a folder. In combination with /DIR the target folder can be specified. This can be useful if the installation process is failing for some unknown reasons. In the extracted folder structure, the TouchDesigner.exe executable can be found in the bin folder.

For a full list of Command-line switches, please refer to this article:

Problems during Installation on Windows OSedit

Installer exits during installation or aborts with an Erroredit

When the Installer exits during Installation without giving a sufficient reason, start a Windows Command Prompt window with Administrator privileges and run:

"C:\MyFolder\TouchDesigner0xx.xxxxx.exe" /LOG="example.log"

Send the resulting log file as a zip or link including a description of the encountered error to Derivative Support

Note: If you persistently run into an issue with the installer, you can try running TouchDesigner without actually installing it. To some extent the installer just copies files to disk and makes sure that some prerequisites are met. All the required files are contained separately in the installer and you can try extracting them using the above mentioned /Extract Installer Command-line switch.

The extracted folderstructure will contain a bin folder in which you can find TouchDesigner.exe

Installer can't continue because of insufficient access rights to folderedit

This behavior can happen during the de-installation phase of a previously installed version. The best way around this is to restart your computer and start the installation process again.

Installer can't remove previous installed TouchDesigner versionedit

In some cases the Installer will quit because it was not able to uninstall a previously installed TouchDesigner version.

Geekuninstaller, available from here, has had good results when trying to resolve install and uninstall related problems.

If the error is persistent, try re-installing the previously installed version of TouchDesigner, remove it via the Windows "Apps & features" Dialog and try installing the new version again.

An unexpected licensing error has occurrededit

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

License Retrieval Error License Retrieval Error

Best success with resolving this has been rebuilding the wmi repository.

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

Open a Command Prompt with Administrative Rights and run:

winmgmt /resetrepository

WMI servicesedit

For some users, simply rebooting caused the issue to fix itself. For other users they have been able to reset their WMI services (used by our license manager) through the following:

If you start cmd.exe (as Administrator) do you get this a successful output such as:

c:\>winmgmt /verifyrepository
WMI repository is consistent

You can also stop / re-start WMI services:

  • C:\Windows\system32>net stop winmgmt
  • C:\Windows\system32>net start winmgmt

Some have also tried:

  • winmgmt /clearadap
  • winmgmt /resyncperf
  • winmgmt /resetrepository

The repository is reset to the initial state when the operating system is first installed.

Problems after Installation on macOSedit

Permissions Error when installing a keyedit

If you get a L1 Key Error when installing your key (see image below), follow these instructions. Please make sure you are in and Administrator account.


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 do not have admin as a group (4th column), then enter this command in the Terminal:

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

Restart TouchDesigner and try installing the key again.

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.
