To install an update, you must always run the respective installation file, XTInstDE.exe for the Pro or Enterprise version and XTInstBasicDE.exe for the Basic version. Install the new version in your existing Xpert-Timer folder and ensure that the path is correct.
In the next step, Xpert-Timer must recognize that this is an update, otherwise the specified storage path is incorrect.
Now go through all the remaining steps until the program starts.
