9.1.0 and 9.1.1 - Can't create New Prototype

Solved Cameron Gull 3 years ago

Macs seem to work fine without issues; however, on Windows 10 on two different computers and licenses, after installing v9.1.0 (and even upgrading to 9.1.1), JustInMind opens with the splash screen. Selecting Web 1280 and clicking "New Prototype" it results in a blank gray screen and nothing happens regardless how long I wait. It's not frozen because I can open the File menu and select New and same issue. Even opening a shared prototype results in the same issue.

We've installed and uninstalled many times.

Could you try this?

- Uninstall version 9

- Go to your user's folder, open the Justinmind folder there and delete any folder that has 9.0 or any version starting with 9

- Download the installer from here https://www.justinmind.com/download

- Install and launch again

Please let me know if this works.

Thank you kindly,



Chloe, looks like that did the trick. Thank you!
