Camtasia Studio: This application has failed to start because WMVCore.DLL was not found

This can happen when running Vista Business N or Windows 7 (or 8/8.1) N because the media components are not installed on that version of Vista.
Please download the zip file below and install those components. It should then trigger Vista/Windows 7 to get automatic updates from Microsoft to install Windows Media Player 11.
Unable to get Camtasia Studio to run on windows 8.1 N series. Looks like the Windows Media Player installation provides the WMVCore.dll required to run CamtasiaStudio.exe. Will there be an upgrade that distributes the missing bits or do we have to wait for MS to release Media Player for 8.1.
Camtasia Studio does link against WMVCore.lib which adds the runtime dependency on WMVCore.dll. This file is included with most versions of Windows. This file is not included with Windows "N" versions, but you can install this support yourself. My searches led me to this page for Windows 8.1: http://www.microsoft.com/en-us/download/details.aspx?id=30685
Cheers for the link, but I had already tried to install this (x64 edition) on my PC. It will not install! ARH. I suspect the Microsoft software has VersionNT64 = 6.1 rather than VersionNT64 >= 6.1 installation criteria.
BTW I'm a software developer. Happy to do further trouble shooting.
I was able to copy WMVCORE.DLL and WMA*.dll from c:\Windows\SysWOW64 is required by a 32bit app or c:\Windows\System32 if required by a 64bit app from a Windows 2012 server computer into Windows 8.1 and the DLL problem went away. Not sure if the media services will work with just these files but at least you can start the app until Microsoft updates the installer. You can probably also copy these files from a Windows 8.0 computer also.
Since Camtasia Studio is currently a 32-bit app, you'll need the 32-bit WMVCore.dll.
In general, using the official installer is recommended over manually copying DLLs. I have no idea why the install would fail on Jamie's system. You'd probably have to contact Microsoft support to dig into that problem.
If you want to try copying DLLs, you'll need to know that on 64-bit Windows, the 32-bit DLLs are found in C:\Windows\SysWOW64, and the 64-bit DLLs are in C:\Windows\System32, which sounds backwards, but that's the way MSFT did it.
