Before You Contact Technical Support

Make sure you are running the latest update of IDRISI
We maintain free Service Updates accessible from the Downloads area of this website. Make sure you are running the latest update of IDRISI by checking your installed version number against the available update. You can check your version number by going to About IDRISI from the Help menu. After updating, check if your problem has been resolved.

Check the Help System for notes on specific modules
If you are experiencing a technical problem with a specific module, or you are receiving unexpected results, the resolution may be found in the software’s Help System. Check the Help System entry for the module you are running, particularly the Notes section for information on data requirements, module limitations and technical notes. The Help System is also accessible from the Downloads area of the website.

Visit the IDRISI Discussion Forum
The IDRISI Discussion Forum is hosted by Clark Labs for the purpose of providing an interactive forum for our user community.  The forum is a place to ask questions, as well as review posts from other users, to solve technical and application issues, and to share knowledge related to IDRISI.

Contacting Technical Support

If the Service Update or Help System has not resolved your problem and you have a valid technical support contract, please contact our Technical Support staff via e-mail. 

For your convenience, a Technical Support Web Report Form is provided.

You should also include the exact text of any error messages you receive.
