I can't find an option for keeping both versions. I have older projects that crash with the new version (22.4), so I have to install V22.0 to open them. I can export them as an XML, but I have thousands of projects and I don't want to have to install 22.0 every single time I need to open older projects, and then re-install 22.4 directly afterward. I want to keep both and I don't see that option anymore. Please help.
