EPLAN has indicated that by EPLAN 2028, traditional dongle‑based licensing will be phased out for new customers. ReHost 2026 lays the foundation for a fully cloud‑native license mobility system, where licenses follow the user identity (SSO) rather than a hardware hash. For now, ReHost 2026 is the essential bridge between legacy and modern licensing.
Even with a perfect process, errors occur. Here are the top issues reported in the 2026 beta tests.
| Error Code | Message | Likely Cause | Solution | |------------|---------|--------------|----------| | EPL-21045 | “Rehost limit exceeded for this license” | Too many rehosts in 12 months | Purchase an additional rehost credit from EPLAN support. | | EPL-8845 | “Target environment not trusted” | Windows Secure Boot or HVCI enabled on target | Temporarily disable Secure Boot during activation (re-enable after). | | EPL-9912 | “Cloud sync mismatch – license ghosted” | License not fully released from old VM snapshot | Contact EPLAN support to force-release the CmActID. | | E-407 | “Invalid rehost ticket” | Ticket expired (valid only 48h in 2026) | Generate a new ticket from the portal. |
Proactive tip: Before any rehost, use the EPLAN License Analyzer Tool (free from EPLAN Support) to check the health of the source license container. This article is based on publicly available information
A major pain point discovered in beta testing is that EPLAN Rehost 2026 raises the minimum system requirements.
| Component | Legacy (Pre-2025) | Rehost 2026 Required | | :--- | :--- | :--- | | Operating System | Windows 10 (21H2) | Windows 11 Enterprise (22H2+) or Windows Server 2025 | | RAM | 16 GB (min) | 32 GB (Recommended for Cogineer) | | Storage | SATA SSD | NVMe PCIe 4.0 (for SQLite local DB performance) | | Network | 1 Gbps (LAN only) | 50 Mbps low-latency internet + LAN (for cloud heartbeat) | | Graphics | OpenGL 4.5 | DirectX 12 Ultimate (for 3D ray tracing in Pro Panel) |
The "Always-On" Caveat: The new Rehosted license requires a "heartbeat" check-in with the EPLAN cloud every 7 days. If a laptop running EPLAN Rehost 2026 goes offline (e.g., on a ship or offshore rig) for more than 7 days, it will enter "Emergency Read-Only Mode." You can extend this to 30 days via the Offline Override policy in the admin portal.
