Starting from January 12, older versions of the platform will no longer function due to the expiration of the code-signing certificate.

If you are using an outdated version (1.141.17 and below), you will need to install the latest one. Here are the links to download the latest versions:

• Original Quantower: https://www.quantower.com/download
• AMP Quantower version: https://downloads.ampfutures.com/quantower

We recommend installing the new version in the same folder to ensure your user settings are preserved.

To find the folder where Quantower was previously installed, you can follow this guide. (https://help.quantower.com/quantower/getting-started/reset-settings-to-default#how-to-provide-settings-for-developers-for-checking-an-issue).

Alternatively, you can manually transfer your settings by copying the "Settings" folder from the old installation directory and replacing it in the new one. This will ensure that all your settings are migrated seamlessly.
