NetSystem package is intended for supporting the designing process of water and sewage networks. The package is composed of software for:

• Calculation of outdoor water supply and sewerage networks complete with graphic editing of network plan and profiles,
• listing and costing of materials for outdoor water supply and sewerage networks design.

The newest, currently available, version of the NetSystem 4 package is: 4.7 Rev 21-xx.xxxx
In order to check which version is currently installed on your computer, program version in the “About the program” window, as “Version” and “Rev.”, must be checked. Performing update from the Internet allows you to obtain the latest version of the software and all associated changes.
As functional development of version 4 is no longer maintained, we have stopped to release information about particular publications and their detailed content.

The InstalSystem 4 package was launched in 2004 and, for many years, remained the flagship product of InstalSoft, delivered to Partners and Users across numerous markets in Europe and worldwide, in around 20 language versions. The last update for this generation of the package took place in March 2020, and since then, the distribution and support for this generation have been gradually phased out.

September 30, 2024, marks the end of support for InstalSystem 4.x, meaning the termination of access to emergency license unlock services and the availability of installation files for InstalSystem 4.x packages on InstalSoft’s websites.

To reinstall version 4.x of the package, it is necessary to have archived installation files saved on a local disk. Additionally, to facilitate work for Users of 4.x licenses, in the absence of access to emergency unlocks, we have significantly shortened the license activation period. This change ensures that, in case the program becomes locked, Users can reactivate the license and resume work after a few days without our support.
