TFS 2005 installation problems

While installing TFS 2005 you may get many error messages during the system health check. Some of the messages may be quite misleading. To find out more details you can open a file called hcpackage.xml (in the folders at, dt or atdt) and find the error message. The file also has WMI queries that are being executed to determine if an error condition exists. Sometimes there are multiple WMI queries that result in a single error message, so you have a much better chance to troubleshoot the problem and resolve the installation issue. You can also try to edit the file and remove the WMI if your environment cannot conform to the TFS 2005 requirements.
