Hi all.
CCleaner 3.24.1850.
Windows Vista Ultimate SP2.
After cleaning with CCleaner, when I launch Excel 2007 the PC remake the installation.
In cleaning options, I disabled all the items in Office.
In EventViewer I see:
Errore durante il rilevamento del prodotto "{91120000-0031-0000-0000-0000000FF1CE}", caratteristica "EXCELFiles", componente "{8BE509B9-BD83-4EEF-99C1-8F6EF615B8FB}". La risorsa "C:\Program Files\Microsoft Office\Office12\XLSTART\" non esiste.
But nobody told to CCleaner to delete the folder XLSTART.
After reinstallation process, the folder has been restored and Excel works fine.
