Troubleshooting - CD Key has invalid checksum

Problem Description:

I am moving to a new server.

I have everything setup, but can't get the license to transfer. On the old machine when I go to the 'deactivate' using my cd-key I get:

"CD Key has invalid Checksum"



Please help me to resolve this error.

Solution:

You will get the error "CD Key has invalid Checksum" when you tried to activate CD KEY of the wrong product.

For Example:

You are trying to activate QODBC Desktop driver using QODBC POS CD KEY or using QODBC Online CD KEY.

So you need to make sure that you are using correct CD Key.

You can't use QODBC Desktop CD KEY with QODBC Online or QODBC POS vice-versa.
