Problem:

When removing Net Express 4.0 Application Server, and performing a manual clean of the Windows registry and installation folder, we reinstalled it onto the same server machine without typing in the serial number and license key while running the install. APPTRACK was used to complete the task, but we are receiving the message License database cannot be created. We checked that the license key fits the product. How do we get a correct installation?

Check if the environment variable ASLMFNET was set erroneously, because it is intended to use ASLMFNET for local machines only, not for a networking license database on a server machine itself. Set the ASLMFNET environment variable to point to the location of the network license database, as follows:

set ASLMFNET=r:\\license-db-dir

Where: r: is the network drive where the license database is. This must be a network drive and not a local one. After deleting ASLMFNET and rebooting the server machine, APPTRACK will put in the serial number and license key.
