As of version 7.5.0.102, the .NET Framework 4.7.2 (formerly 4.5) is required.

In case that Simple Shop software informs you that your operating system needs to upgrade the system framework to a newer version 4.7.2, download the .NET framework from our website and install it.
Installation is absolutely necessary, otherwise the Simple Shop software will no longer work after the new upgrade.
Also, with the new version, support for Windows XP (32 and 64bit) will be permanently discontinued.

Download .NET Framework 4.7.2:

If you need help upgrading the .NET system framework, contact the Simple Shop support team. The upgrade service is charged on the basis of the time spent, but not more than 1 service hour, which is charged according to the valid price list.
