Existing ILWIS 3.x users

Existing users of ILWIS version 3.0 or later, both ITC and PCI customers, are entitled to upgrade to version 3.3 free of charge.

  • Download the executable above, and install ILWIS 3.3.
  • When upgrading from ILWIS 3.1 or later to ILWIS 3.3:
    There is no need to register ILWIS 3.3, as ILWIS 3.3 uses the same registration code as ILWIS 3.1, 3.2 and upgrades.
  • When upgrading from ILWIS 3.0 to ILWIS 3.3:
    You are supposed to have received an ILWIS 3.1 registration code in May 2002 at the e-mail address you provided in the registration form.
    • If you use this 3.1 registration code, there is no need to register ILWIS 3.3, as ILWIS 3.3 uses the same registration code as ILWIS 3.1.
    • However, if you are an ILWIS 3.0 user and have NOT received a 3.1 code, please fill out the registration form again (see link below) and contact us at ilwis@itc.nl.

ILWIS 3.3 can be installed next to ILWIS 3.2.
