Finally understood your simple solution. Simistornij regulator napryazheniya dlya induktivnoj nagruzki. The installer is asking for the Location parent folder for the Folder ' ProPlus.WW' and NOT for the location parent folder to the file ' propsww2.cab' Thanks The_SLX YESSSS! Just use (as an example). C: YourInstallFolder Office 2013 Professional Plus x64 (copy and paste path from Windows Explorer to the text box on the error dialog).
Also, if ProPsWW2.cab is actually missing (which, in my case was missing), you will have to get it from the install CD (no, the installation does not copy this file intact; it is a cabinet file and all files are extracted from it during installation).
Install Office 2013 Errorr 'Setup cannot find ProPlus.WW ProPsWW2.cab'.
