There are no more "perpetual" licenses.  As of 2006, all licenses are granted on a 2 year basis. (based on payment of maintenance fees, per the "pay for use" clause)

Even if they were still issued, prices of licenses are based on the bundle.  Bundle prices vary greatly.

ok
Then I will try to ask them the list of prices for the different bundles.

thnk you

From what I understood, the licenses are only like "rented", thus the 2 years validity. If you want to use them more than 2 years, and not buy them all over again, you have to pay for maintenance fees, and after 2 years, they send a new license. But I also heard (it might be wrong information..) that in some special cases, it's possible to "buy" the license from Dassault, so it would be permanent, and you wouldn't have to pay for the maintenance, but you wouldn't get the updates either I think...
And for the prices of the bundles, they vary much as mentioned, but depending on how many licenses you are going to buy, you can always negociate a discount on them.
