Recurring "Invalid License Key" Message

 

SOLUTION: 

During the installation of nQuery Advisor certain information needs to be written to the Windows Registry. In order to do this the user must have permission to access the registry.

 
In general this is restricted to administrators and sometimes even administrators will not have full permission to access the registry. In order to install and register nQuery Advisor you should do the following before running the installation:

  1. Go to the ‘Start’ menu and in the search box type “regedit”. There should now be a program called regedit in the menu. Click on this icon to start the program.
  2. You should see a set of folders in a window on the left.
  3. You need to select the folder called HKEY_LOCAL_MACHINE.
  4. Double click this folder and got to the subfolder SOFTWARE
  5. Navigate down through the folders until you reach this folder: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\NonEnum
  6. With this folder selected select Edit -> Permissions… in the menu at the top.
  7. In the new window you should see a list of users. If your name is in this list select it and skip to step 10). If not, click on Add.
  8. In the box in the new window type in your username. Then press Check Names. Your full username should now be displayed. Click Ok.
  9. Now your name should be listed so select it.
  10. In the lower box you should see a column of check boxes. Under the heading “Allow” tick all of the boxes. Then press Apply and Ok.


Once this is complete, run the installation and the software should install correctly.
