When I try to install FrontPage Extensions on a domain through Helm, it fails and I get the following error in the logs
2005-05-03 00:15:01 Website.IWeb_InstallFP Unknown error while installing FrontPage: The FP extension failed to install. FP Extensions responded: (-666) Error 5 opening registry key "SOFTWARE\\Microsoft\\Shared Tools\\Web Server Extensions\\Secure/LM/W3SVC/2133:".

This is an error unrelated to Helm - as you can tell from the error log, it mentions a problem with the FrontPage registry key. However, the following article from Microsoft may help:
If it doesn't fix the issue, you should contact Microsoft directly for further support.
