KeepAlive automatically pings your officeclip site every 30 minutes to ensure that the asp.net process remains alive (required for background processing of scheduled reports). It is automatically installed with OfficeClip but in some cases it may not install correctly.

1. Go to Control Panel > Administrative Tools > Services and check if OcKeepAlive.exe is installed. if not follow the steps below:
2. Open the command prompt as administrator and change directory to the path where the officeclip is installed.
3. Run the command "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe" OCKeepAlive.exe.
4. Run another command net start OCKeepAlive
5. Next Run this command REG ADD HKLM\Software\OfficeClip /v mainUrl /t REG_SZ /d https://yoursite/officeclip/default.aspx (this url may differ and depend on where    OfficeClip is installed)
