I've been struggling with this for a while now ... reaching out to see if anyone smarter has figured this out ...
From any other machine I get the generic Runtime error. From the WHS console, I get more detail:
Could not load file or assembly 'Interop.SearchAPI' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
along with a bunch of exception stack info (I'll post if that helps).
I've searched and the only thing I found was the suggestion to look at IIS and make sure that the remote app pool has Enable 32-bit Apps (in advanced options) is false and that all pools are set to .NET v.4. I've also made sure all updates are applied.
Short of doing a clean install (which I _DO NOT_ want to do), I'm ready to give up.
Any ideas? If I have to reinstall from scratch, it's probably going to be a complete migration to something else, given the roadmap of WHS from MS.
Cheers, Marc
