I had also problem with Session Drummer in Sonar X3 under Windows 8. After several uninstall and install finally I installed from Sonar X2. Now is OK.There must be some problem with Sonar.  

The same thing also worked for me, but after updating the Microsoft redistributables, Session Drummer worked correctly when the X3 version is installed. I preferred to use the X3 installation, because the Session Drummer dll is larger, so I figured it might be an improved version. (I don't actually know if it is or isn't). So it doesn't appear that it's a Sonar problem ... It looks to be an issue of outdated redistributables from Microsoft. Perhaps Cake keeps up with the latest Microsoft updates while some of us (like me) have old or missing/corrupt redistributables. The older X2 software apparently is compatible with the older distributables I had on my system prior to updating, while X3 was not and required updating them.

Got the same issues here, but the Noel-Fix does not work for me, so it must be something else other than a redistributable (I downloaded and installed all of them).  I've now downloaded Dependency Walker and have created the DWI file, but reading it cannot figure out which file(s) is/are giving problems.  Something about API-MS-WIN-CORE-WINRT.  I've opened a ticket though, and hope support will be able to tell me where the problem lies ...

If you post a link to the file I can take a look at it.

Hi Noel, many thanks ... the link : https://www.dropbox.com/s...SessionDrummer_x64.dwi

Your depends log is clean. There are no dependency problems on your machine. Are you sure your scan path includes session drummer? Support can probably walk you through resolving this. I think your issue may be something simpler. 

Thank you very much Noel.  AFAIK (I am not on the system right now) the scan path is okay ... it's one of the first things I looked at.
 
I will contact support to resolve this.  Again, thank you and have a great Xmas.

Thank you for the Dependency Walker program. I ran it and it was not able to open Session Drummer and game me a list of issues. I do not understand much of what I am seeing. Where should I send it? Thank you.

IESHIMS.DLL is highlighted in red, everything else is black. Is it enough information?

That's an internet Explorer issue:

I don't think it's related to your actual issue, but try upgrading to Internet Explorer 11 if you haven't already to resolve this one.

I have Windows 8.0, isn't it already has IE 11? can it cause issue with opening Session Drummer? Any other suggestions would be appreciated.
