What is dbDOS™ PRO 4?

A product of dBase, LLC. dbDOS™ PRO 4 is the next generation of the standard single user engine for previous dbDOS™ applications. The new dbDOS™ VM (engine) now features a live file system and is over 38% faster than the previous release. dbDOS™ PRO 4 includes support for both 32 and 64-bit versions of the currently supported Microsoft operating systems. The new version is as simple to use as the prior editions, just backup your existing software, install dbDOS™ PRO 4 and run. It is that simple!

dbDOS PRO 4 is the most reliable way to enable virtually any DOS-based application to run on Microsoft’s Windows® Vista, Windows® 7, Windows® 8/8.1, Windows® 10, Windows® Server 2008 and Windows® Server 2012. It includes support for both 32 and 64-bit versions of these operating systems. It is not a version of dBASE, just the DOS Emulation/Virtual Environment needed to run DOS programs on Windows 64bit.

What is dbDOS™ PRO 4N?

dbDOS™ PRO 4N builds on all the great features of dbDOS™ PRO 4 and adds multi-user networking support. Just install dbDOS™ PRO 4N on all the computers that you want to run the multi-user applications and go!

What does dbDOS™ PRO 4/4N support?

dbDOS™ PRO 4/4N is specifically engineered to work best with dBASE CLASSIC™, the re-bundled version of the last release of the world class version of dBASE V for MS-DOS. However, dbDOS™ PRO 4 works well with dBASE™ III+, dBASE™ IV (Version(s) 1, 2, 3), and as stated before dBASE™ V for MSDOS. dbDOS™ PRO 4 will work with any of the older MS-DOS based programs. We have customers using Lotus 1, 2, 3, Word Perfect 5.1, FoxPro, and many other classic applications. dbDOS™ PRO 4 is the easiest way to keep your mission critical MS-DOS based applications up and running for years to come
