Hello jeswantjm,

It is probably caused by wrong access rights of Temp folder.

To reset the permissions:
1) Click on the "Start" button from an account with Admin rights
2) Choose the "Run" option.
3) Please type the "cmd" (without quotes) command to the command line and confirm by clicking on the "OK" button (or press Enter).
4) Type "cacls %SystemRoot%/temp /e /g Everyone:F" press Enter
5) Type "cacls %temp% /e /g Everyone:F" press Enter

Thank you
