I know this is OLD software, but I like it. I recently bought a new computer, and wanted to install MS Streets & Trips 2011 on it (I had used various versions, starting with 2001) on my old computer. Both my old and new computers are on Windows 10, with the new computer being Pro and the old one Home. S & T still works fine on my old computer. However, when I install it on my new computer (it installs fine; no errors), I am unable to successfully activate the license. I have a valid license key, the activation screen accepts it and I get a message that the software has been successfully activated on this computer. However, when I go to launch the program, it again asks me to enter my license key, and I'm back to the beginning. If I select "Use trial period," I get a message that my trial period has expired. I've tried activating over the phone; same result. Contacting Microsoft directly just results in being told they don't support the software any more and use Bing Maps instead, which I don't like. Any help? Thanks much!
