Office 2010 SP2 install error

I was trying to install SP2 for Office 2010 Professional Plus on an older workstation. The installer was asking for the location of ProPlusrWW.msi – for some reason, the MSOCACHE folder was missing.

Resolution:

Copy all files from office 2010 setup disk
D:\Ms_Office_Catalog\ProPlus.WW\
to folder
C:\MSOCache\All Users\{90140000-0011-0000-0000-0000000FF1CE}-C\
and rerun update.
