I'd swear that I got this working previously on another computer, but I can't seem to get the Telligent Search service installed for v11.1.0.9731 (downloaded late May). The installation procedure for search is relatively straight-forward. Below are the contents of \Community\Search\data\logs\nssm.log.
The file it's getting the Access Denied error on doesn't exist (C:\Verint\Community\Search\server\start.ini)
