Updates and Upgrades Subscription
FOR PERPETUAL LICENSES WITH A VALID UPDATES & UPGRADES PERIOD (VERSIONS 8 AND 9 WITH ACTIVE UPDATES)
Warning: this page is only for holders of a perpetual license whose Updates & Upgrades period is still valid and who have NOT yet subscribed to an Updates & Upgrades subscription.
Check the expiry of the Updates & Upgrades period for each of your licenses in your User Panel.
DO NOT PROCEED on this page if you are in one of the following cases:
- your software is on subscription (quarterly/semi-annual or annual) and you do not own a perpetual license
- the Updates & Upgrades period of your perpetual license has already expired: in this case use the Software Updates page for your version
- you already own a valid Updates & Upgrades subscription for your license. You can check your subscription status on the My Subscriptions page
What it includes: all updates and version upgrades released during the subscription period, plus the Heatsim connection to AI, the MCP server that connects the software to AI assistants (Claude, ChatGPT, Cursor, VS Code, Codex). The Heatsim connection only works while the Updates & Upgrades period is valid.
Multiple licenses or Server license: if you own several licenses of the same software, or a Server license with multiple concurrent users, set the quantity with the selector next to the Subscribe button: the subscription must be taken out for each license (or each concurrent user).
If you have doubts about the Updates & Upgrades period of your license or if you cannot find your software, send an email to Dartwin.
Extension options
Prepaid 24, 36 or 48 months: it pays off. Compared with renewing year by year, with the prepaid plans you save. Example: Mold PRO 2D costs € 120 per year with the annual renewal, but only € 95 per year with the 36-month prepaid plan (€ 285 paid in advance for the whole period).
+ Web License: with the “+ Web License” options you add, for the whole duration of the subscription, access via Web License: you use the software on any computer by activating it with username and password, without transferring the license.
Your license still includes updates and you want to add the Web License right away? Write to Dartwin: we will send you a discount code that deducts the months of updates already covered from the first payment.
All prices exclude VAT. Unless cancelled, the subscription renews automatically at expiry.
From: €80,00 +vat / year
