Error Code 603- Activate - After Last Update

marmour07 · ‎March 22, 2026

TurboTax 2025 - Standard. I received notification to update my activated version. After it installed and Turbotax restarted it said to activate my version. I have already activated my version but entered in my valid account and activation code. It said I have already 3 versions activated and it cant activate this one. Not a good situation, help.

So I called support. It was not a pleasant experience. They cant figure out how to remove the PC from the license code. Then they told me that since it was bought from Costco - Online, not their problem and they couldnt help me. Seriously. Its Intuit's license code and the product was downloaded from Intuit website. Just unbelievable. So I have a product which is valid, paid for. And since it asked me to reactivate and it cant its not their problem. Go figure.
