# How to Deploy CS Professional Suite in a Multi-User Network Environment

[CS Professional Suite](https://www.oneupnetworks.com/cs-professional-suite-hosting/) is a trusted accounting software suite from Thomson Reuters, widely used by US tax and accounting firms for multi-user collaboration. Deploying it on a cloud server enables secure, remote access for teams without on-premises hardware.

## System Requirements

CS Professional Suite requires a full Windows Server installation (not core mode) for network/multi-user use, as it needs .NET components. Key specs include:

| Component | Minimum | Recommended |
| --- | --- | --- |
| Processor | Intel/AMD 2 GHz 64-bit | 3 GHz+ multi-core [https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx](https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx)​ |
| RAM | 4 GB | 8 GB+ [https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx](https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx)​ |
| OS | Windows Server 2012 R2, 2016, 2019 (64-bit) | Latest supported [https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx](https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx)​ |
| Network | Wired, high-speed | Business-class broadband [https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx](https://cs.thomsonreuters.com/support/systemrequirements/portals.aspx)​ |

Avoid wireless networks and non-Windows NAS to prevent file-locking issues.

## Step-by-Step Deployment Guide

Follow these steps for a cloud-based multi-user setup, such as on Azure VM, AWS EC2, or a hosting provider like OneUp Networks.

### **Choose and Provision Cloud Server**:

Select a Windows Server 2022 or 2019 VM with recommended specs. Enable RDS roles via Server Manager > Add Roles > Remote Desktop Services (Session Host and Licensing). Activate RDS CALs for multi-user access.

### **Install CS Professional Suite**:

Download the latest installer from your Thomson Reuters account. Run SETUP.EXE on the server to install shared program files (e.g., to F:\APPS\WINCSI). Use UNC paths like \server\share\WINCSI for flexibility.

### **Obtain and Install Licenses**:

Use CS Connect to download network licenses. Install them on the server once; workstations pull them automatically. Verify via Setup > System Configuration.

### **Configure Workstations**:

On user devices (Windows 10/11), run the workstation installer from the network share. Connect via RDP to the server or publish apps as RemoteApps. Use full UNC paths for shortcuts.

### **Test and Secure**:

Launch apps from multiple sessions, test file sharing, and enable MFA, firewalls, and audit logs. Update via CS Connect regularly.

## Cloud Provider Options

- **Self-Managed (Azure/AWS)**: Full control; provision Windows Server VM, install RDS. Cost-effective for 5+ users but everything is to be self managed.
- **Hosted Providers**: Virtual Office best alternative [OneUp Networks](/) offer pre-configured CS Suite environments with compliance (SOC/ISO). Ideal for smaller firms with 24/7 support and all apps can be integrated.
