The built-in update mechanism seems not to work.
If the update of your ETS5 did not work with the ETS5 built-in update mechanism, then please use the full setup that can be found here.
Due to the change of the TLS version of the update servers to 1.2, problems may occur when downloading the update under Windows 7. These can be avoided by activating TLS 1.2 in Windows 7, see here.
When using the full setup, your existing projects are not affected. However, please keep in mind the following:
- It's always strongly recommended to backup your projects before any software update. To backup your projects, you can simply export them (see here: https://support.knx.org/hc/en-us/articles/115003360545-Import-Export) or use the Project Archive (see here: https://support.knx.org/hc/en-us/articles/360002948000-Project-archive)
- If you are updating from an older (<ETS 5.7.0) ETS version, please note that after you have installed the latest version, you will have to update your project(s) you are intending to work with.
