• Minimum 800x600 screen resolution using 96 dpi. (1024x768 or higher is recommended.)
• 32-bit color (recommended)
• CD-ROM drive for installing programs onto the hard disk.
• High speed wired network is recommended for multi-user version. Wireless networks are not recommended due to performance and reliability issues.

1. Requires System Configuration
2. The free copy of PracticeMaster Basic provided with Tabs3 requires that Tabs3 is also installed
3. Word Document Assembly requires Microsoft Word. HotDocs Document Assembly requires HotDocs and either WordPerfect for Windows or Microsoft Word compatible with your version of HotDocs.
4. An additional 436MB is required when the optional Tabs3 training videos are installed.
5. An additional 352MB is required when the optional PracticeMaster training videos are installed.

Platinum Server

The following system software and hardware is required for the server computer on which the Platinum Server will be installed:

• Platinum Server software.
• Platinum versions of the software (i.e., 90000 series serial numbers or 95000 for Platinum SQL).
• A multi-core processor is recommended.
• The network must use the TCP/IP protocol.
• 2GB RAM is the minimum memory requirement of the Platinum Server.
• Ensure that plenty of free disk space is available. Temporary files created on the server can be quite large. Minimum free space of four (4) times the data set size is recommended. Each HotBackup requires enough disk space for the entire data set.
• Windows Server:  Microsoft Windows Server 2008/2003 (either 64-bit or 32-bit version), Windows Server 2008 R2, Windows Small Business Server 2011/2008/2003 (either 64-bit or 32-bit version), Windows 7, or Windows XP Professional. Recommended that all current Service Packs be installed. A 64-bit operating system is required for Platinum SQL Server.
  Note: When running Windows 7 or Windows XP, you are limited to the number of concurrent connections and may be restricted by the connection limit in that operating system.
  Note:  Running Platinum Server under Windows Vista is not recommended.
• Workstation:  Windows 7/Vista/XP. Recommended that all current Service Packs be installed.
• High speed wired network is recommended for multi-user version. Wireless networks are not recommended due to performance and reliability issues.

Additional information regarding Platinum Version requirements

Platinum Version software is designed so that it can run on modest server hardware but can take advantage of more powerful servers.

• Adding RAM to a server is the least expensive way to improve server performance. While Platinum will run on a 512MB server, at least 2GB RAM is recommended for best performance.
• Using Accelerator technology in Platinum, the faster the server's CPU(s), the less time it takes to process reports. A multi-core processor is recommended.
• In order to use HotBackup, your server must have enough free disk space to hold copies of the entire data set. You control the number of copies to keep but you must have room to hold at least three.
• The faster the server's disk subsystem is, the less time it takes to perform a HotBackup.
• A Microsoft Server operating system is recommended (e.g., Microsoft Windows Server 2008 or 2003). Using a non-server operating system such as Windows 7 or Windows XP will work, but they were not designed as server operating systems and have some limitations, such as concurrent connections.
