Issue:Unable to Install End Point Protection Client on Server 2003
Other Symantec Products in that Computer:Backupexec, Symantec End Point Protection Manager

Didn't run Cleanwipe because it will wipe Symantec End Point Protection Manager
Didn't do manual Uninstallation because it will affect other Symantec products
Current Version:11.0.5002.333

I was able to install MR3 earlier,now  i uninstalled MR3 and tried to Install MR5,now i am facing this issue.

Steps Tried:
 Tried to Install liveupdate installation successful
 While trying to Install Symantec End Point protection through MSi it stops at Install Cache
Tried the same steps with managed and self Managed both hangs at install cache
 Checked for SEP_Inst in %temp% it is not generating the SEP_Inst logs searched for that logs it is not present.
 Event Log Service was Started and Automatic.

Able to Install Windows Installer Cleanup,Ran Windows Script .5.7 for Server 2003,Restarted the Computer
Able to install Windows Installer, 3.1unregister and reregister the windows installer.
However stil the Installation hangs at create install cache

Any Suggestions?
