OpenVPMS can be installed on either a unix system (most commonly a Ubuntu* server), or a Windows system. For Windows, for small practices you can install on a desktop or laptop running Windows 7, 8 or 10; for larger practices it may be better to use a Windows Server operating system.
*NOTE: OpenVPMS requires MySQL 5.5, which is included in Ubuntu 14.04. Later releases include MySQL 5.6 or MySQL 5.7 which are only supported via configuration changes.
32 or 64 bit version? Both Java and MySQL are available in 32 and 64 bit versions. For larger systems (where you will want to run MySQL and Tomcat with large memory allocations) you should use the 64 bit versions. Otherwise the 32 bit versions are adequate.
Download the MySQL Community Server 'Generally Available (GA) Release'.
On Windows, the MySQL installer may require that the Microsoft .Net Framework 4 be installed. This is available from:

NOTE: if you are upgrading from MySQL 5.1, see the MySQL 5.5 Reference Manual - Updating MySQL for instructions on migrating the existing MySQL 5.1 data to 5.5.
MySQL:
This may be included in the MySQL server installation.

If you wish to use the External Edit facility then the following software is required on all workstations that will edit documents in OpenVPMS:
NOTE: later versions of the Java Platform deprecate or remove Java Web Start which is required to launch External Edit.
