System Requirements


This article contains minimum and suggested system requirements for servers to host the PSIfusion web application.

Note that the minimum system requirements will guarantee functionality, but not optimum performance. The recommended system specifications represent the environment for which the PSIfusion application was intended to run. This does not exclude newer platforms, hardware, or system architecture unless otherwise noted.

If your system specifications fall below the minimum requirements, you may have to upgrade your system's hardware and/or software before installing and configuring PSIfusion. Having a system that is below specifications does not necessarily infer that the application will not work, however PSIGEN cannot support a system with hardware or software that is below the minimum requirements. Please contact the Support Team for more details.


PSIfusion is supported for both 32-bit and 64-bit platforms. We recommend, but do not require, a 64-bit server platform for optimum performance.

1.  This amount of disk space is generally required for the operating system and framework, and their updates. More may be required depending on the operating system version, and more disk space will be required for storage of scanned documents.

2.  Microsoft Internet Information Services (IIS) will not serve a web application to more than 10 concurrent users when running on a non-server operating system.  PSIfusion will only be supported on non-server operating systems for demonstration purposes.
