If an update is started directly from the application with some older versions of G DATA products, this can lead to problems. The reason for this is a prolonged non-updated and obsolete state of the software in use.
If you run into the following error message when updating (see screenshot), you should reinstall your software to continue receiving updates.
You will find an up-to-date setup file in My G DATA on our website, which you can use to update your G DATA product. For comprehensive instructions on how to reinstall your G DATA product for every supported operating system, see How to install and activate your G DATA product.
