Trying to upgrade from Teaming 1.0 to Teaming 2.0.

Per the upgrade instructions, I have copied the existing installer.xml into the installation folder for Teaming 2.0.

The next step (page 141 of teaming doc) says "Remove old license files from your Teaming site and make sure that you have a license-key.xml file in the same directory with the Teaming 2.0 installation program."

I take that as copying the original license-key.xml file into the Teaming 2.0 install folder.

When I try to execute the Windows installer, I get:

Installation cannot proceed without a valid license while executing
"tclError "Installation cannot proceed without a valid license""
(procedure "openLicenseKey" line 13)
invoked from within.....

Am I doing something wrong?
