Timing Commander - Installation Error Message: Error 0x80072ee7:

Example Message: Error 0x80072ee7: Failed to send request to URL: http://download.microsoft.com/download/0/5/D/05DCCDB5-57E0-4314-A016-874F228A8FAD/SSCERuntime_x86-ENU.exe

Cause: the installer has failed to download the .NET or Runtime SQL installers. This may be due to firewall settings or no internet connection.

Fix: verify that there is an internet connection present and check firewall settings. Some lab environments security restrictions prohibit PCs from having internet access. In that case, the installers for the supporting software must be downloaded elsewhere and ported using a USB drive. Download the .NET and SQL Compact installers using these two links:

.NET framework installer: http://www.microsoft.com/en-us/download/details.aspx?id=17718 

SQL Compact 4: http://www.microsoft.com/en-us/download/details.aspx?id=17876
