This week, while helping a client do a brand new BizTalk Server 2020 installation, I encountered a brand new, strange error that I had never seen in all my years working in BizTalk Server:
[2025-05-20 11:26:11:0556 Error Configuration Framework]Feature: [Group] Failed to configure with error message [Catastrophic failure]
Yes, you read it right: Catastrophic failure! It seems like a message from a horror movie or a comedy sketch.
Cause
This is indeed a strange error message that doesn’t give us many details. Going through the log file does not bring us better evidence:
- [2025-05-20 11:26:02:0994 Error BtsCfg] Catastrophic failure
- [2025-05-20 11:26:02:0994 Error BtsCfg] e:\bt\57588\private\source\setup\btscfg\btscfg.cpp(1877): FAILED hr = 8000ffff
- [2025-05-20 11:26:03:0041 Error BtsCfg] The server has not been configured.
To configure the server, run the BizTalk Server Configuration wizard and configure the Group feature.
We found that UAC was enabled, and we were running the BizTalk Server Configuration Console without administrator privileges. And we were getting this strange error.
Solution
By running the BizTalk Server Configuration wizard using administrator privileges

We could work around that error and successfully configure BizTalk Server 2020.
