Update to V15 Does not Work #98529
https://thebrain.zendesk.com/agent/tickets/98529
Hello Walter,
Thank you for the update.
I appreciate you trying the installer from C:\temp. Since the same result appeared, please also complete the second step, open Windows Settings › Apps › Installed Apps, uninstall any existing versions of TheBrain 15, and then run the installer again from your local folder (such as C:\temp or Desktop).
Once that’s done, let me know if the behavior changes or if you still see the same error so we can continue from there.
Best regards,
John
