I've tried loading and then un-installing a dozen times - still get the same error. I've never had a problem before this. I'm going to have to dust off my old computer (hopefully it still works) if Turbo Tax can't fix this issue.
This Turbo Tax FAQ will provide a solution for the error code 1334.

I am having the same problem and neither of the links is working for me.
I found that I changed my display settings to 600x800 and then started TT - it worked. I only had to do it once and then after changing back to the preferred higher resolution it worked just fine.
