I don't think it's Session Drummer related.

Also in order to resolve that IE issue as you already have IE11 you could try upgrading to Windows 8.1 (available for free in the Microsoft Store) but please backup first. If you don't see it in the MS Store you need to run Windows update first.
 
Your Session Drummer issue is another issue, so I don't want to detract too much away from this thread....

I updated my 2 other computers to Win. 8.1, but this one has 190 plugins installed (accorging to VST manager)- I do not want to take my chances. But this is what Dependency Walker revealed when I opened SD.dll with it.

Acronis True Image is still on sale for the next few days which will image you partitions to a separate hard drive:

Windows 8.1 can be regarded as basically a service pack for Windows.
 
Cheers...

Right... it wiped out my other computer- I lost USB support and had to reinstall OS. It was traumatic. Also not all drivers are supported. I am earlier adopter with updates, but this one I had bad experience.

Yup - I have DELIBERATELY chosen not to upgrade to Windows 8.1 at the moment, and will wait quite a while prior to going for it.

windows 8 has its own system image software
 
In Windows 8 and Windows RT, open the control panel and click/tap on the Windows 7 File Recovery icon.

A) In the left pane, click/tap on the Create a system image
 
 
I use it all the time for my weekly back ups.

Yup that's definitely good advice, Win8 is certainly a huge improvement when it comes to backups, but you really don't get the flexibility like you do with other third party tools sadly:

But any backup is better than no backup.

Ok, can we talk about Session Drummer? I have paid expansions for it installed and songs that are using it. It needs to be available and working. What is it that I need to do? Unselect all options but SD in Sonar X3 installation and install it again? I am thinking- if the problem is dependency file, reinstall would not help anything.  

Sorry to jump in on this late. Please, do not mess with Win8 at all yet. Which version of IE are you running (open IE and select Help->About IE)
 
Edit: The IESHIMS.DLL file is part of the install of IE 8 and above. Have you tried updating/reinstalling IE yet?
 
Edit2: I just used DW on my machine and am also missing the "specified file" but my session drummer runs fine. I would first recommend what you mentioned above and re-install Session Drummer only. If that does not help, I would next suggest re-installing the X3 patch for the version you are running.

I am on another computer now, but IE version was something like 10.0.11. I looked everywhere on Microsoft web site for updated version- it only pressures me to update to Win. 8.1 and get IE 11.
 
The SD file is there- I can see it. I copied it to another location but it does not go trough the Sonar plugin scan. How do I reinstall the parch? Just run X3d update again?
 
Also when I installed X3, I only installed part 1 to 4, did not install "Additional content", because I had SX2 installed. But now that I am thinking- I am not sure if I installed Additional content when I installed SPX2, as I was thinking- I have SPX1, but it was on my old computer. I thought- I heard- Sonar X3 does not offer SD any more and is not  having it in installer because it was replaced by Addictive Drums, and we only have it because we had older versions. Is there SD in X3? Thank you.
