As they say wrong things come in hand when you dont want it to.
We have a major release coming Friday and we are facing the following issue while Installing the application(MSI).
Please see the log file and please suggest any workarounds.
Note:
a)This happens only on certain systems and not all.

Thanks,
Sreenath
