Windows Agent Install or Upgrade fails on 64 bit OS Print


Problem

An upgrade-in-place of a Windows 64-bit Agent fails with the message:

Unable to create the detached server: This application has failed to start because the application configuration is incorrect.

Or a manual upgrade or install fails with errors such as:

The system cannot execute the specified program.

or

SEVERE - An error occurred processing sigsetup.inf

Solution

64-bit Windows Agent needs to run Microsoft .NET Framework 3.5. In the Add/Remove Programs screen make sure that version 3.5 is installed. If it is not, use the Windows Update service to download and install the software.
