The license is invalid
I had a local installation of Sitecore 7.2 + Coveo 3.0 March 2015 (patch #995). Indexing & searching was working fine. I updated to the following software level:
- Coveo Enterprise Search 7.0 x64 (8047)
- Coveo Search API 8.0.893 - Coveo for Sitecore 72 3.0 (1188)
After a few attempts, I got a clean install. The Diagnostics page indicates success/green lights for everything except "Coveo Security Provider".
I noticed near the end of the upgrade an advisory that Support has expired. I assume that refers to the free dev site, because we have an ongoing support contract with Coveo.
In any case, CES Admin won't get past the license prompt, and the log contains several "The license is invalid" events. Oh, and indexing fails fast with the same message.
