Should you receive the following error during TurboTax Program Update
Error after rebooting PC and starting TurboTax 2011
You find yourself unable to open the program anymore to get any further help or updates. The only way to correct this problem is download a manual update file from Intuit’s website. Be sure to pick the correct year and computer operating system. In my case this was 2011 and Windows.
After running this manual updater TurboTax operates correctly once more.
This tax season has been technically challenging. I first discovered that H&R Block TaxCut software did not support electric vehicle credits. I got a refund for TaxCut and purchased Turbo Tax instead. Then my install of TurboTax failed, requiring some fancy foor work to overcome until Intuit posted a resolution. That was followed by my return being rejected by the IRS because TurboTax did not submit all pages of a multi part form, that was part of my schedule C filing. The most recent update failed as described above, but I finally overcame what I hope to be the last hurdle to getting my $7,500 tax credit for the Nissan LEAF I purchased last year.
I have re-transmited my taxes via e-file once more and await the response from the IRS.
