Hi Kada,
Could You please provide some additional details?
What version of IE is installed on this machine? (Please provide full version from Help > About Internet Explorer)
Could you please also provide version of IE from registry (Open your registry and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer)
Please run Windows Assessment Scan on machine where installation of ms12-037 is actually failed and send us with STPatchAssessment.log & STPatchAssessment.xml from client directory C:\Program Files\Altiris\Altiris Agent\Agents\SoftwareManagement\Software Delivery\{6D417916-467C-46A7-A870-6D86D9345B61}\cache\
Thank you in advance,
Roman
