Bidcon client

The following table displays the minimum and recommended requirements to run the Bidcon client in an installation in which both the Bidcon client and the database are locally installed on the same machine:

	Minimum	Recommended
Operating system	Windows 7 SP1	Windows 10

Required software

Microsoft SQL Server Express 2012 or later, with the latest service pack installed
Microsoft .NET Framework 4.8

For multi-user installations in which the Bidcon database is located on a different machine from the locally installed Bidcon clients, the hardware and software requirements above apply to the Bidcon clients, apart from the fact that a Microsoft SQL Server database does not need to be installed on the machines onto which you install Bidcon.

Dedicated server for Bidcon database

We recommend Windows Server 2016. See Microsoft’s system requirements.

Terminal Server for Bidcon

The following table displays the recommended requirements for installations in which Bidcon is installed in a Terminal Server or Citrix environment

	Requirements

Architecture Overview

Bidcon is a fully-featured estimating application that can be used to produce detailed estimates for your projects. Bidcon can be installed as a single-user application on one machine, or as a multi-user application in which a database is installed on a server machine and individual client applications are installed on different PCs.

Bidcon comprises the following elements:

The Bidcon client applications. Many users running the client application on different PCs on a network can access estimations that are stored in a central database.

The Bidcon database. This is a Microsoft SQL Server database. The Bidcon database can be located anywhere. If Bidcon is installed as a single-user application, the database must be installed on the same computer as the Bidcon application; if Bidcon is installed as a multi-user application, the database can be located anywhere.
