As millions of people are updating their PC to Windows 10, they are bound to run into some compatibility issues. This particular Windows update was the easiest one that I have done. I go back to the DOS days. One error message that did stump me for a bit was about a missing WMVCore.DLL. It has to do with media files.
The problem with this error message is I wasn’t sure what program I needed to reinstall. Was it the program that I wanted to use, Camtasia? Or, was some other program involved? I guessed wrong and tried to reinstall Camtasia. I figured it was the source of the file.
Long story short, the file I needed is part of Microsoft’s Windows Media Feature Pack. You can find it at the link below. And as you might expect, Microsoft sites work best on their browsers so I would start with their Edge browser.
You’ll need to choose which flavor of Windows your PC uses. Be advised this is a large download and you will need to restart your PC.
Update: 08/24/2016: It seems that the Windows 10 Anniversary update broke some apps for me and gave a similar error message. These included Camtasia Studio and reading PDFs with Microsoft Edge. I tried reinstalling the download referenced above, but no luck. I stumbled upon a thread in the Microsoft forums that pointed me to a solution.
I’d suggest reading through the entire thread as several solutions are referenced. Some of them didn’t work for me.
