As per the current policy we are not providing old versions of Telerik OpenAccess ORM clients for free - they are however available on demand for our DevCraft collection license holders.
In case you would like to use the free version only, we would recommend you to either upgrade to the latest release, or use the approach described in this documentation article in order to setup the project in a way that would allow working in a team with different versions of OpenAccess ORM installed. Note that all team members working on the domain model itself - using the Visual Studio designers and wizards we are offering, still have to have OpenAccess ORM installed locally.
Alternatively, you can consider the DevCraft Complete or DevCraft Ultimate collections - apart from access to older versions, you will become eligible to 24h support services. The Ultimate option will also bring you phone assistance and remote assistance through screen sharing. Of course, you will also have the opportunity to use other award winning Telerik controls and components as well, so that you can base your applications on a proven framework of products.
Let us know if you have any questions.
