service pack 1 update getting unspecified error

Hi,

I am new to InstallShield and using InstallShield 2012, when i install and run it for first time i get service pack 1 prompt to update.
When I update, I get "unspecified error. Please contact the software vendor or try again at a later time.


If i go through software manager i get a different error, as "script error"

An error has occurened in the script on this page.
line: 275
char: 7
error: unable to set property 'display' of undefined or null reference
code: 0
url: ...

If i press yes, it doesn't show any update, so i am not able to upgrade to sp1.

Attached the screenshot of the error.

Thanks,
raja
