After uninstalling the previous release 2.4c and deleting the folder C:\Users\My Name\ARISExpress I cannot install 2.4d. (I downloaded the file twice.) After starting, I get a message, that there is a release 2.4d available. In the upper left corner I see 2.4c.

Hilfe->Programm aktualisieren shows always, that there is a 2.4d available.

I use Win10 fall creators update and Java 1.8.0_131

What went wrong?
