i've been getting this error that says 'error 1712. One or more files required to get restore to its previous state could not be found. restoration will not be possible. setup failed. rolling back changes.' while i was reinstalling microsoft office professional plus 2010. it started when i installed microsoft visio 2013, i decided i wanted the other 2013 products of office too so i uninstalled office 2010 but then the 2013 setup failed. when i tried reinstalling office 2010 i got the error stated above.. and i uninstalled visio 2013 but it says it cannot successfully uninstall so i had to force uninstall it using IObit uninstaller. after that i tried to install again the old office but i'm getting the same error again. i don't know what to do next, will somebody help me pls?
