This applies to SharePoint 2010 and 2013.
Issue
While installing CU on SharePoint 2013 Server, we got an error given below.
It says The installation of this package failed.
Cause
- Missing cab files, all the files cab and exe file should be in the same folder.
- Also, check the size of the files that you downloaded and double check with Microsoft site.
- Above two are not the reason for failure.Now, check the name of your cab file. It should be like ubserv_1.cab or ubserv_2.cab; it cannot be ubserv_1(1).cab or ubserv_2(1).cab. This can also cause installation failure.
- Download CU from the Microsoft site and install it again.
Hope, it helps.
Happy SharePointing.
