We recently sold two copies of CRM 4.0; one upgrade from CRM 3.0 SBE and one new license.
The quickest way to kick-off your CRM project is to use a 90-day trial version that can be downloaded here. To upgrade from trial to full version you will just need to enter customer product key.
We had some problems while trying to find product keys for our customers. Menno describes where to obtain CRM license keys… very simple procedure for volume licensing customers is:
1) Login to eOpen or MVLS
2) Download MS CRM product image
You will find product key inside your image file. You will not find product keys enywhere else!
3) Enter CRM product key via CRM deployment manager
4) Register your CRM (you will need license information provided by Microsoft)
