If you’ve been following my blog in recent months you are aware that Microsoft is now blocking macros downloaded from external sources (e-mails, internet, …). If you aren’t aware then I urge you to review:

Now, I wrote about unblocking the macro so you could use the files again, refer to:
but recently a fellow MVP brought up a weird error when they tried to unblock a file and I thought I’d post the information here for all to benefit from.
Nature of the Problem
After checking the Unblock property and clicking on the Okay button, we would receive a series of error dialogs:
…
Too many posts were made to the semaphore.Windows
…
An assertion failure has occurred.Windows
and ultimately the file ins’t unblocked.
The Fix
So what’s the solution then?!
Actually, it is very simple, at least in my experience.
Open the file properties dialog by right-clicking on the file, selecting Properties from the context-menu and ensuring the file is NOT read-only, so make sure the Read-only checkbox is unchecked.
then check the checkbox to Unblock the file. That’s it.
And yes, Microsoft could most certainly make their error message make sense, but who are we kidding, that will never happen!



I was hours looking for this solution. To imagine that it was a simple “Read-only” check box…
THANK YOU SIR!
