Here to Help

If you are a 4D Partner, a holder of a support contract, or have registered a 4D product in the last 30 days, you're eligible for 4D's world-class tech support online at no additional cost.

4D provides free, online-only tech support using the form below.


Certain levels of the 4D Partner Program also entitle you to free tech support by phone.


Paid technical support by telephone or by form is also available on an individual, case-by-case basis. Please contact your 4D representative for current prices.


Maintaining value in your investment

As a company policy, 4D sells and supports not only its current version, 4D v11 SQL, but the previous version of the product line as well. If you’re still using 4D 2004, you get the support you expect, and the migration guidance you'll want when the time comes.


4D 2004 has entered the Sunset phase of the product lifecycle. While 4D 2004 products are still available for purchase for compatibility purposes, we highly encourage you to begin new development projects with 4D v11 SQL
