I spent HOURS on the phone yesterday with Customer Support supervisor Kareem based in Atlanta (this was after almost an hour with first-level Customer Support who needed to get clearance to connect me to a higher level). He said he has had HUNDREDS of such calls and his only fix was a work-around that sets up a new profile on my Windows PC to use it exclusively for TurboTax. That worked in the sense that I manually updated to R21 and TT did indeed launch. But I read of another option and it also works (better for me). When the update installer reports the error, start the Task Manager and then find the Intuit Installer on the list or programs running. Use End Task and then TT will launch. Until this is fixed, I think the update patches probably need to be installed manually, then use the simple steps above to bypass the updater because it does not recognize that TT has been updated and will keep trying to do so with the error that prevents TT from launching.
