i downloaded a older version of the DLL and changed to Read only which wndows wont be able to replace itFrom what I can tell, the Windows 10 Update that loaded on my computer on 9/22/2016 installed a new version of msmpeg2vdec.dll. If I open a Dashware project that worked last week, I get an error message that says "The procedure entry point MFCreateTrackedSample could not be located in the dynamic link library C:\Windows\System32\msmpeg2vdec.dll." This DLL imports the MFCreateTrackedSample function from another DLL, MFPlat.dll, which Windows 10 also updated on 9/22/2016. So the problem could be with either of those new DLLs I guess. A System Restore to last week would likely fix it, but only until the update reinstalls. And it's a huge one this time.
