A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi, the screenshot shows that Excel itself is not the problem. Microsoft Office Professional Plus 2024 is not activated, so the Activation Wizard appears when Excel starts.
If this Office was supplied by your company, connect to the company network/VPN and try activation again. Professional Plus volume-license editions normally need activation provided by your IT administrator (KMS/MAK). See: https://support.microsoft.com/en-us/microsoft-365-activation-licensing/office-install/using-product-keys-with-microsoft-365
If you purchased Office yourself, check which Office license you actually own at https://account.microsoft.com/services and install Office from there. If you have a new unused product key, redeem it at https://microsoft365.com/setup
Once the correct Office license is activated, this activation window should stop appearing.
