I have a couple windows from a 7.9.10 project that was imported into 8. There isn’t anything special about these windows (power tables, templates, buttons, script, etc.) that stands out to me from the 20-30 other windows in the project that upgraded fine. Any ideas based on the error below? Or do you need an export? I’m getting this both in the designer and launcher. ```auto 12:36:08.509 [AWT-EventQueue-0] ERROR com.inductiveautomation.factorypmi.application.model.WindowCache - Unable to open window

Still seems to be happening !! I am importing the window from 7.9.10 to 7.8.5. I have done this before but never had this issue !! ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/0/00d54c82be7e1a66ac0e9f176e3a742994bb3bfa.png) ---

Probably a different error since it you aren’t using 8.0, but I’m guessing it isn’t a fan of downgrading versions, and that might be the root cause. ---

as @grietveld said, this looks like a different error (or cause, anyway) and is likely caused by trying to import a window from a newer version into a older version, which is absolutely unsupported. ---
