Missing plugins when switching to another computer

I bought new computer and installed all plugins i had in old computer, ive copied my projects from old computer and i scanned all my plugins.
When ive opened some projects, there were only plugins like camel crusher with settings i did in old computer, other plugins like fabfilter or vallhala were missing (but i have them there) so probably settings are missing too. I can normally open and use new plugins from start but that would be nightmare to do my projects again. Hope someone can help. Thanks!


Can you add the plug-in as a new instance? are you sure you are using the same version of the plug-in, which has been used in the old project?
