Can't Load Turbotax 2024 on 3rd PC - Error code 603

Gerbear111 — Mon, 02 Feb 2026 05:41:02 GMT

Hi there, I'm trying to activate last year's Turbotax 2024 Standard download on my other laptop, so I can compare page by page to my Turbotax 2025. There are only 2 laptops that it has been loaded on right now. When I try to activate the Turbotax 2024 on the 3rd laptop I get the error code 603, as per attached. Please rectify so I can load on this 3rd laptop. Thank you.

Sorry but your reply is useless.

After calling the support number I am transferred to another #, then another one, etc., turning in circles.

What is the # for Tech Support?

Why did I buy this product?

I'm sorry to hear about your experience. I've requested a call back from the assigned team. It takes 24 to 48 hours for a callback. They will contact you and assist you with this.

We appreciate your patience. Thanks.

Hi, TT_Anika:

Well, I did receive a callback from Tech Support offering me a free TT 2024 license code ... but what I really needed was a TT 2025 activation code/product key (I initially replied to an existing post from Gerbear111 because I cannot post myself on this web site - Access Denied, no permission, etc.).

So please make the same request as before, but for TT 2025, and have the code emailed to me.

Thx a lot!

@ypci I'm glad you got a call back and that the TurboTax 2024 issue was resolved. According to the process, I am unable to request a code for Tax Year 2025 because we must adhere to certain protocols. However, you can contact product support directly, and they will assist you over the phone.

https://turbotax.community.intuit.ca/turbotax-support/en-ca/help-article/tax-return/contact-us/L1h8P3E0x_CA_en_CA?uid=m4j5o7no

They are now open seven days a week, 9 a.m. to 12 a.m. EST.

Thank you!
