C. Activation & Managing Licenses

Ans. IIACAD licenses can be used both in Online/Offline Mode. Incase of Online activation, the machine needs to be connected to the internet (the license will be checked periodically once in 30 days) and incase of Offline activation, the machine need not be connected with the Internet.(We need an active internet connection on a different machine to activate an Offline license only during the time of the offline activation).

Ans. The user can simply log out from one machine from IIACAD and use the same credentials and login into IIACAD on a different machine to switch machines.

Ans: Yes. Users can be added/removed in the Organization by an Admin/Co-Admin using the Graebert Customer Portal.

Ans: End User whose license of IIACAD Software was activated on 30 Sep 2020, purchases Subscription renewal only on 1 Nov 2021, the validity period of such Subscription shall be from 30 Sep 2021 to 29 Sep 2022 and not from 1 Nov 2021 to 31 Oct 2022.

Ans: End User (a) whose license was activated on 1 Jan 2021 did not purchase and activate any Subscription renewal, but requires services under IIACAD Software Subscription in February 2023 or (b) requires services under IIACAD Software Subscription in February 2025, but had activated the last Subscription renewal on 1 Jan 2022; shall not be eligible to purchase Subscription renewal but instead shall have to purchase an Upgrade.

Ans: The default method to activate a permission key is to assign a permission key to a Graebert Account (using Email ID) and to use the Graebert Account credentials as a login inside IIACAD. Assigning this permission key can be done from the software IIACAD or online on the Graebert Customer Portal. When the user will login in IIACAD the system will need Internet to check the validity of the license on the Graebert servers. After log in the user no longer needs Internet and can work offline for up to 30 days. IIACAD only needs access to the Internet at least once in every 30 days to check the status of the license.

Ans: If the user cannot have Internet access on the computer at least once every 30 days he may decide instead to do an Offline Activation. Offline activation doesn’t require any Internet access on the computer that will be activated. Instead an activation code will be generated by IIACAD on the computer that will be activated and this code has to be entered in the Graebert customer portal to activate the permission key. The offline activation implies that the license will be locked definitely on a single computer but the consequence is also that the user will not be able to log out and easily switch the license from one computer to another. It is therefore recommended to use always the online activation unless the license will be used on a computer that has no access to the Internet (not even once every 30 days). Each license activation requires an individual Email ID. Offline license also requires only the HOSTID of the machine and not the MAC ID/IP Address of the machine.

Ans: Network License of IIACAD requires to install a license server (NLM) on one computer or one server to which all the Flex license users (clients) need to be connected. A minimum of 3 floating licenses is required for a Flex license (no network license of 1 or 2 floating licenses). When a Flex license user is launching IIACAD, the program will check with the license server if any license is available. We require 1 Email Id for activating the network permission key. The NLM license file will be generated based on the Ethernet ID of the server/any computer on the same network.

Ans: Company Admins can also use the Admin space of the Customer Portal to invite, centralize and manage the licenses of their organization. They may for example remove the license for one user and assign it to another user, unless the license was activated for offline use and therefore bound to a specific computer. ADMIN of the Organization will have all the rights to add/remove users from the Organization and the users will need to consult the Admin of an Organization for further information. Individual users of an Organization will have no possibilities of managing a license of IIACAD.

Ans: Please write a mail to and the details will be shared accordingly.

Ans: The Perpetual license is a time-unlimited license for one user for the version of IIACAD purchased by the customer. It includes a 12 months subscription to receive upgrades for IIACAD + Email support. When this first subscription expires, it can be extended with successive Subscription renewals. If the subscription expires and it is not renewed, the user would lose the rights included in the subscription but can keep using the license of IIACAD. The Subscription Renewal and Upgrade shall be priced at 25% and 50% respectively of the then applicable License Fee. Refer clauses C5 & C6 of FAQ explaining the dates applicable.

D. Support & Queries

Ans: Incase of Offline license activation of IIACAD, the license activation requires only the HOSTID of the machine and not the MAC ID or the IP Address of the machine. For Flex license activation we require Ethernet Id of the server/any computer on the same network.
