Many people have asked me about availability of a downloadable Microsoft Dynamics NAV 2009 demo. Unless you are an existing Microsoft Dynamics NAV customer on a support plan, or a Microsoft Dynamics partner, you can’t download a demo version from a public Microsoft web site.
You can download your copy from a community web site though – check the links at the bottom of this post. Be advised that some of the downloads are larger than a gigabyte, which might not be too download friendly.
So, if you can’t download the demo, there is still a great option for trying Microsoft Dynamics NAV 2009: go to the Microsoft Dynamics NAV Test Drive website at http://www.dynamicsnavtestdrive.com/ and access the online virtual environment where you can try Microsoft Dynamics NAV 2009 for free.
