Hi, I have installed Adabas 6.3.0.03 for community edition for learning purpose. I’m using the license key provided in the setup.exe for activation. But the activation is getting failed saying that my OS is not compatible with the Adabas 6.3.0.03 for community edition. I’m using Windows 7-Ultimate on Dell Vostro machine. Someone kindly help me. ---

For the Adabas community edition no license file is required; you can use Adabas without activating a license key. However, without a license key there are some restrictions in Adabas. ---
