update problems

  • hello,


    my Kemper has 2.5. at the moment and I wanted to update to 2.7.4. but ervery time I tried it says: update has failed. update cannot be used.


    also tried to use another version 2.7.0. and then 2.6.0. and always after 49% the error occures....


    any tips?

  • used another usb stick and it works!!


    Interresting: the stick I used first was my dedicated "Kemper USB Stck" I used for almost 2 years for every update and backup and never had any problems
