# Installing EPP 8.5

This section includes platform qualification, installer prerequisites, preâ€‘checks, installation steps, and troubleshooting instructions.

Supported Operating Systems

Seqrite Endpoint Protection supports the following platforms:

- Windows 11 Enterprise
- Windows Server 2019
- Windows Server 2022

Note
Support for Windows 11 Pro and Windows Server 2025 may be included in a future release.

## 2. Installer OS Qualification Logic

The Seqrite installer validates the target operating system before installation. Supported versions include:

- Windows 11 Enterprise / Pro and above
- Windows Server 2019 and above

If the system does not meet the minimum OS requirement, the installer must prevent installation and display a clear message.

## 3. Installer Framework and Technology Requirements

The Seqrite EPP installer is implemented using Java and install4j.
The installer package must include the following thirdâ€‘party components and internal dependencies:

- Java 21
- MongoDB 8.0.12
- NATS Server 2.11.8
- WildFly 36
- Client packages
- Standâ€‘alone tools
- Bundled utilities required for service startup and configuration

All components must be versionâ€‘locked and validated for compatibility.

## 4. Preâ€‘Installation Checks

Before installation starts, the installer must perform the following mandatory preâ€‘checks:

### 4.1 Hardware Checks

Â· Disk Space:
Minimum 50 GB free disk space
(This includes space for antivirus definitions; final requirement may change based on performance testing.)

Â· RAM:
Minimum 4 GB Free space.
(Based on Microsoft recommendations for Windows 11; subject to change based on performance testing.)

Â· CPU:
Minimum 4 cores

### 4.2 System Feature Checks

- AXV (virtualization) check: Enabled
- Locale: Must be en (English)
- OS version:
  Minimum version = Windows 11 / Windows Server 2019

If any check fails, the installer must block installation and provide remediation instructions.

If a screen with message ‘Missing System Requirements- Windows defender is currently active and may interfere with the installation process.’ popups while installing EPP, then use the below command on powershell to uninstall the Windows-Defender
