em-Client update

emClient Update lässt sich nicht auf meinem Laptop mit win 10 64 bit installieren.
Es kommt kurz vor Schluss der Fehlercode 2502 oder 2503.
Wer kann helfen?
Vielen Dank mal schon vorab.

If you are comfortable executing these steps, give this a try:
(1) Delete any installation files you have downloaded.
(2) Uninstall eM Client, making sure to NOT delete your database directory when asked. This will ensure your settings and data remain in place.
(3) If it exists, delete C:\Program Files (x86)\eM Client
(4) Download and install the latest version from Release History.
(5) The latest version of eM Client should then start with all your data in place.
