How to uninstall RE:Vision Effects plug-ins
Go to the Add/Remove Programs Control Panel and uninstall the plug-ins there (they will be listed by product name). Or, go to the Start menu and select the product name, and then pick the uninstaller listed as a sub-menu for the product.
For plug-ins installed after Nov 1, 2016: Go to /Application/REVisionEffects in the Finder. Then go into the subdirectory for the product you want to uninstall. Inside that directory is an “uninstall” directory. Simply run the uninstaller from there! If you did not save your original installer, download the latest installer, install (yes, install!) the product again, and then follow the instructions in the previous paragraph to uninstall. If you have the original installer, and it’s dated before Nov 1, 2016, re-run the original installer. When you get to the place where it asks you to specify the installation type, pull down the menu at the top of the dialog box. Sometimes it says “Standard Install”, in other installers it might say something else (in the example below it says “Install Twixtor 5, AVX2 version”). Select “Uninstall” to remove the plug-ins.
For plug-ins installed after Nov 1, 2016: Go to /usr/local/revision. Then go into the directory for the product you want to uninstall. Inside that product subdirectory will be an ‘uninstall’ directory. Simply run the uninstaller program found there. For plug-ins installed before Nov 1, 2016: remove the appropriate plug-ins in /usr/OFX/Plugins (for OFX plug-ins) or /usr/discreet/sparks (for Autodesk Sparks). Then if you have node-locked licenses, remove the appropriate node-locked license files in /usr/local/revision
