Invalid checksum

Recommended Posts

Hello,

 

5 unsuccessfull attempts later, any help welcome...

 

Each time I agree and start installing the latest upadte from 5.090.17 to 5.110.15 it stops later or sooner and states "There was an error in checksum validation."

 

Is there a tip, a fix, or a way to downlod on the PC and install frome this verified downloaded file ?

 

Thanks in advance,

 

Jean-Jacques
