This tool collects a variety of information about the system to help diagnose driver and client issues. The collected data is:

• Operating system name and version including 32/64bit
• Installed Platform version
• Memory size
• Common Language Runtime version
• Key directory locations
• List of drives and free space
• List of COM ports
• List of loaded assemblies
• COM Registration entries from the registry
• Version information for key ASCOM files
• Version information for key ASCOM GAC files
• Version information for some installed applications that use ASCOM drivers
• List of driver registration and compatibility messages. On a 64bit OS a driver's suitability for running in a 64bit application is also reported.
• Contents of ASCOM releated installer setup logs
• Results of several hundred application functionality tests on Platform components and Simulators
• List of Platform errors from the Windows ASCOM error log

When the "Run Diagnostics" button is pressed, the information above is collected into a log file titled ASCOM.Diagnostics.hhmmssssss.txt that will be found in "My Documents\ASCOM\Logs yyyy-mm-dd". This file should be forwarded, together with other log files in the directory, to the person who is helping you.

A suite of functional tests are also run to confirm that the installation performs as expected.
