Installer Overview
What RasterexInstaller.exe installs, the installation flow, and what to do after installation.
Before running the installer, ensure these requirements are met.
- Windows Server or Windows 10/11
- Administrator rights (Run as Administrator)
- IIS installed with Static Content feature (required for all packages)
- Node.js installed (required for running the db backend)
For production environments, deploy the installer on a dedicated Windows Server host with sufficient resources for IIS, the DB backend, document processing, caching, and concurrent user activity.
- Operating system: Windows Server 2019 or Windows Server 2022.
- Processor and memory: Minimum 4 CPU cores and 16 GB RAM recommended.
- Storage: Minimum 100 GB SSD recommended, with additional capacity planned for uploaded files, cache data, logs, and exported documents.
- Network: Reliable connectivity between the web viewer, DB backend, database server, and client users.
- Ports: IIS should be available on ports 80/443, and the DB backend uses port 5203 by default unless configured otherwise.
- Database access: Connectivity to a supported database server: Microsoft SQL Server, MySQL, or PostgreSQL.
Download the current supported installer for new deployments and upgrades.
