Minimum System Requirements

To function effectively, most users of Expert Estimation will require a computer with the following minimum specifications:




A single-socket dual core 64-bit (x64) processor (with Hyper Threading).

A single-socket dual core 64-bit (x64) processor (with Hyper Threading).

A single-socket quad core 64-bit (x64) processor (with Hyper Threading) per 5 connected client instance.

2 GB (gigabytes) RAM.

4 GB (gigabytes) RAM plus 1 GB RAM per 10 connected client instances.

2 GB (gigabytes) of available hard disk space for installation of software.

8 GB (gigabytes) of available hard disk space for installation.

Storage space needs to be considered for the number of projects on the server.

DirectX 9 graphics device with WDDM 1.0 or higher driver.


1024 x 768 display (1920 x 1080 recommended) with 32-bit colour.


A 10/100 Mbps network connection (either wired or wireless) is required for communication with non-local servers.


Windows 10 or Windows 11.

(Incompatible with Windows 8 or below)

Windows 10, Windows 11, Windows Server 2012 or above.

(Incompatible with Windows 8 or below)

Microsoft .NET Framework 4.6.2.

Microsoft .NET Framework 4.6.2.

Expert Estimation requires activation to operate.

A periodic internet connection is required for ongoing software activation (phone activation is not available).

Connection to the internet is required for submitting error reports and usage information.


Note: Based on the features, quantity, and size of projects stored on an Expert Estimation Server, additional system resources may be required and should be determined further in conjunction with Pronamics Support. Load balancing servers are currently not supported by Expert Estimation.


When establishing a multi-user instance of the Expert Estimation Server, disk read and write data throughput needs to be considered for both the number of concurrent projects open and the size of each of these projects.

In most cases, multi-disk storage systems designed for performance are more suitable than a single disk approach.

Note: Solid State Drives (SSDs) are preferable over mechanical hard disks, however, SSDs are not a requirement for the software to operate.
