One of the file format plugins (dtx_aWMFDirect.d1x) for Windows 32 and 64 relies on Microsoft Windows' media components. With some versions of Windows, like Vista Business or 7/8/8.1/10 KN, Microsoft does not include these components by default. To fix this error, you can either delete the dtx_aWMFDirect.d1x and dt_WinMedia.d1x from the installation folder, which will disable WMV/ASF read/write, or install the missing components from Microsoft.
To install them, please use the installers below:
- Windows 7: Media Feature Pack for Windows 7 N and Windows 7 KN
- Windows 8: Media Feature Pack for N and KN versions of Windows 8
- Windows 8.1: Media Feature Pack for N and KN versions of Windows 8.1
- Windows 10: Media Feature Pack for N and KN versions of Windows 10
- Vista/XP: WMFDist11-WindowsXP-X86-ENU.zip
