Downloaded Excel File Says Macros Are Blocked Mark of the Web Fix
You downloaded the add-in from the video, did everything right - and Excel greets you with a red SECURITY RISK bar and refuses to run anything. No Enable Content button, no explanation. This is not your file failing. It is a Windows security stamp doing its job - and it has a proper, one-minute answer.

The mark is invisible and the bar is blunt, so most people either give up or go hunting for a setting to disable - the one response you must not have. This page explains what stamped your file, the Properties checkbox that is the entire official fix, and where the line sits between unblocking a file you trust and disarming your PC.
The red bar on a downloaded file
SECURITY RISK Microsoft has blocked macros from running because the source of this file is untrusted.
The file itselfDownloaded from the internet - Windows tagged it on arrival
The code insideNever even ran - Excel refused before asking you
The red bar wording is real. Unlike the old yellow bar, it has no Enable Content button - the decision is made at the file, not in Excel.

Why Excel Blocks the File Before Asking You
When a file arrives from the internet - a browser download, an email attachment, a chat forward - Windows quietly stamps it with a mark: this came from outside. It is called the Mark of the Web, and you never see it happen.
Since 2022, Office treats that mark strictly for macro files: macros are blocked outright, with the red bar above. This is protection working as designed, not a fault. For years, booby-trapped Excel files from email were one of the biggest infection routes on earth; the red bar exists because the yellow Enable Content button was too easy to click without thinking.

The One-File Fix - Unblock It in Properties
For a file whose source you know and trust - like the add-in linked under the video you just watched - the fix is at the file itself:
Close the file in Excel first
Right-click the file in its folder and choose Properties
On the General tab, at the bottom, tick Unblock next to the line This file came from another computer and might be blocked
Click Apply, then OK
Open the file again - the red bar is gone and the function works
The stamp is removed from that copy permanently. Every fresh download is a fresh decision - which is exactly the point.

If It Came Inside a ZIP, or It Is an Add-In
Two wrinkles worth knowing:
ZIP files pass the mark to everything inside them. Either Unblock the ZIP itself before extracting, or Unblock the extracted Excel file afterwards - one of the two must lose its stamp
An add-in file (.xlam) is unblocked the same way - Properties, Unblock - and you must do it before installing the add-in through the Add-ins dialog, or Excel will load it in the same blocked state
If your office manages your PC, policy may re-block or forbid unblocking - in that case the honest route is your IT team, not a workaround

What Not to Do - Three Tempting Mistakes
Do not switch off macro protection for all files in the Trust Center. Unblocking one trusted file is a decision; lowering the setting is removing the door
Do not download an unblocker tool. A stranger's program that promises to fix blocked macros is a worse risk than the block ever was - the built-in Properties checkbox is the whole fix
Do not unblock files whose source you cannot name. If you cannot say exactly where a file came from and why you trust it, the red bar is giving you the right answer - leave it blocked

There is no Unblock checkbox in Properties. Where did it go?
Three usual reasons: the file is still inside a ZIP - extract it first, or unblock the ZIP itself; the file was copied from a network location that does not carry the mark in the same way; or your office policy controls the setting. If the checkbox is absent and the red bar persists, the file likely came through a path your IT team manages - take it to them.
I clicked Enable Content on other files before. Why does this one have no button?
Because this is a different, stronger block. The yellow bar with Enable Content is Excel asking you about a file it is willing to run. The red bar means the file carries the Mark of the Web, and for marked files Office no longer offers the button at all - the trust decision moved to the file's Properties, where it cannot be clicked by reflex.
Is unblocking a file safe?
Unblocking is safe exactly when the trust is real: you know the source, you expected this file, and you would defend the decision. It removes the internet stamp from that one copy only. Unblocking a file a stranger sent you is removing the warning from the one thing it was warning about - do not.
