See if ADMIN's suggestion may help in the below link. It addresses the same error message encountered in Hoster, only in the download stage. Since there was no response, it must have taken care of it. Wouldn't think it would matter which product is involved, considering the nature of the problem as ADMIN saw it..
I'd be tempted to do a new download and install fresh.
