If you have used the Service Level Dashboard  then you know if can be really powerful tool. If you have not , please refer the link:  http://blogs.technet.com/b/systemcenter/archive/2009/11/20/service-level-dashboard-for-operations-manager-2007-r2-videos.aspx

There have been few instances where the SLD Installation might rollback and you attempted this over and over again. The Windows Installer Logging could help you track down the issue and one of the interesting one is when you have a past failed solution stuck in the SharePoint. Once you enable the windows installer verbose logging the log file would reveal multiple things, check if you see the below extract

 Installer log

============

MSI (s) (7C:10) [16:08:27:301]: Invoking remote custom action. DLL: C:\WINDOWS\Installer\MSI67F.tmp, Entrypoint: CAQuietExec

CAQuietExec: 

CAQuietExec:   A solution with the same name "sld_solution.wsp" or id "fe57ceb5-b12d-4a06-add2-cb466a4d02c8" already exists in the solution store.

CAQuietExec:  C:\Program Files\Service Level Dashboard 2.0\SLD_Solution.wsp: The Solution installation failed.

CAQuietExec: 

CAQuietExec:  Error 0xffffffff: Command line returned an error.

CAQuietExec:  Error 0xffffffff: CAQuietExec Failed

Action ended 16:08:31: InstallFinalize. Return value 3.

============

 

Solution :

Delete the failed instance of the SLD Solution by running the below command

stsadm -o deletesolution -name "SLD_Solution.wsp" 

 ( I would recommend running this command by your sharepoint admin once)
