Prototyper 9.1.1 does not start

Solved Giorgio Sciani 3 years ago

Trying to run Prototyper 9.1.1 but it does not start.

Running the .exe, It displays the Prototyper logo for 1-2 seconds and after nothing happens.

I have also version 8.7.9 installed and it work perfectly. I have a Professional license for 6 users.

I tried to start it several times, tried to uninstall and reinstall, restart the machine and also to log-off and then log-on again on the 8.7.9 version, but nothing change.

I use Windows10 Enterprise.

Hi Giorgio,

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

Let me know if that works


Hi Victor, I follow your instructions and now it works.
