Hi,

Mostly reinstallation in the only solution to this problem, but before that
we can try the below step.

1. With the error message on the screen (sku011.cab error), hit CTRL+ALT+DEL
to get the task manager
2. Go to PROCESSES tab.
3. End the process of MSIEXEC.EXE under your user name. Please note there
will be 2 MSIEXEC.EXE, one under system and one under your name or login name.
End the process for the one which is under your user name or else there might
be problems with the office.
