I get the same issue as this. The addin is installed, set to ‘Loaded’ in the addins, and the icon appears on my ribbon. Ĝheck which Quick Views version is loading: The dll from Inventor 2022 is loaded (but my Inventor is 2020). Uninstalled Inventor 2020, then re-installed Quick views Uninstalled and installed Quick Views again (like 10 times) Made sure folders for Quick Views and the dll files are not ‘Read only’. I was using Quick Views just fine on this exact setup a month ago. However when I open quick views while inside a drawing, an empty instance of Quick Views launches and nothing happens after. The addin is installed, set to ‘Loaded’ in the addins, and the icon appears on my ribbon.
