    Lightroom 6 standalone upgrade does not install - does not validate the serial number




      I have bought (Adobe store) yesterday and downloaded Lightroom 6 standalone upgrade (I own lightroom 4).

      During the installation in Windows PC I get the following message: "We are unable to validate this serial number for Adobe Lightroom. Please contact the support"


      - the Internetconnection is fine

      - checked etc/host

      - double checked both serial numbers


      It is just impossible to install the LR6 upgrade on my Windows PC. There were no problems installing and running LR4...

      Any help would be greatly appreciated...
