This error message has come up recently when trying to install Camtasia Studio. From researching the error it does not seem specific to just Camtasia Studio as other programs are running into the same exact problem. From what we can tell this is being caused by this Windows Update.
Uninstalling that update should resolve the issue.
Go to control panel > programs and features. On the right hand side click on view installed updates.
Scroll down until you see the group labeled Microsoft Windows and look for (KB2918614).
