Dear @Christian B. Sax,
Thank you for posting your question in the Microsoft Q&A forum. I understand you are trying to download Project Professional 2024 after redeeming your product key, but every time you click the x64 or x86 link, you only see a “Service Unavailable” error. You have already tried several times over the past 14 days, and you still cannot get the installer.
From the error message, it seems the download service for Project Professional 2024 is having technical issues on the server side. This usually happens on Microsoft’s download portal, not because of your device or browser.
Before we continue, may I check if you had a chance to review the automated replies provided by our AI on the support portal? Sometimes those steps help identify the cause.
To better assistance, could you please confirm following information:
- Where did you purchase the product key? (Microsoft Store, authorized reseller, Workplace Discount Program, Volume Licensing, or a third‑party marketplace)
- Which page are you using to start the download?
- Do you see Project Professional 2024 under Services & subscriptions after redemption?
- Are you signed in with the same Microsoft account that redeemed the key?
- Does the error appear immediately after clicking 64‑bit/32‑bit, or only after a brief redirect?
- Have you tried InPrivate/Incognito and a different browser (Edge/Chrome/Firefox)?
- Have you tried from a different device or network (with VPN/proxy turned off)?
- When did you redeem the key?
- Do other downloads from your Microsoft account work normally?
Your detailed response will help us diagnose and investigate the issue more efficiently.
I truly appreciate your patience and understanding. If I misunderstood what you’re looking for, feel free to let me know or share a screenshot. I’d be happy to help further!
I'm looking forward for your reply. Thank you for your cooperation.
