Sysprep Fatal Error With IE 10 (FIX)

My fellow system administrators, there is a bug with sysprep and Internet Explorer 10 in Windows 7. My department maintains a Windows 7 image that we use on all our desktops. Today I installed some Windows updates which included Internet Explorer 10. When I tried to sysprep the machine like I usually do I received an error that a fatal error has occurred while trying to sysprep the machine. After looking at the logs (setupact.log and setuperr.log) I discovered what the issue was:

Error      [0x0f0085] SYSPRP LaunchDll:Could not load DLL C:\Windows\SysWOW64\iesysprep.dll[gle=0x000000c1]

It turns out that Internet Explorer 10 was the culprit. Strangely, ‘iesysprep.dll’ does exist within C:\Windows\SysWOW64. I have posted about it on the TechNet forums and it appears I am not the only one having this issue. Another user on the TechNet forums, sgennadi, has posted what appears to be a solution. It calls for modifying sysprep registry values and changing them back from SysWOW64 to System32. I personally have not tried his/her solution. I reverted back to a previous image and installed the new updates again, minus Internet Explorer 10, and sysprep works fine. Personally, I will be waiting for Microsoft to address this in a Windows Update before I upgrade to Internet Explorer 10.

I decided to add the proposed solution here in case anyone wants to fix it themselves. Again, credit goes to sgennadi for the solution.

After installing IE10, open the registry editor (regedit). You should make a backup of the registry before making any changes in the event that something goes wrong. You can do this by choosing File > Export and make sure you select ‘All’ under ‘Export range’.

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep\Cleanup

Locate: Value Name {EC9FE15D-99DD-4FB9-90D5-5B56E42A0F80} Value Data C:\Windows\SysWOW64\iesysprep.dll,Sysprep_Cleanup_IE
Replace the value with: C:\Windows\System32\iesysprep.dll,Sysprep_Cleanup_IE

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep\Generalize

Locate: Value Name {EC9FE15D-99DD-4FB9-90D5-CE53C91AB9A1} Value Data C:\Windows\SysWOW64\iesysprep.dll,Sysprep_Generalize_IE
Replace the value with: C:\Windows\System32\iesysprep.dll,Sysprep_Cleanup_IE

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sysprep\Specialize

Locate: Value Name {EC9FE15D-99DD-4FB9-90D5-676C338DC1DA} Value Data C:\Windows\SysWOW64\iesysprep.dll,Sysprep_Cleanup_IE
Replace the value with: C:\Windows\System32\iesysprep.dll,Sysprep_Cleanup_IE

Now you should be able to run sysprep successfully without receiving the IE10 related error.

    We had this issue with Sysprep using VMware Linked Clones – Windows 7 64bit Enterprise. It affected 2 pools but not the third pool. All had the IE 10 updtate. Uninstalling the Internet Explorer 10 update, under updates in Programs and features, resolved our issue. VMware Tech support found this blog while we were on the phone with this issue. Jesus, you helped to make my day a lot better!! Thank you!

    Locate: Value Name {EC9FE15D-99DD-4FB9-90D5-CE53C91AB9A1} Value Data C:\Windows\SysWOW64\iesysprep.dll,Sysprep_Generalize_IE
    Replace the value with: C:\Windows\System32\iesysprep.dll,Sysprep_Cleanup_IE

    Are you sure Sysprep_Generalize_IE has to be replaced with Sysprep_Cleanup_IE?

    Fantastic! worked for me! just remember to run in an admin account. I also had to change the permissions on the entries before it would save them.

    I was stuck on this as well. When I went in to make the changes to the REG, the machine stated give some generic error about writing back to the REG. I had to change the permissions on the string to edit it and then changed them back. I’m about to rerun sysprep and see what happens..

    You can do the above or just uninstall IE10 for this particular issue. I ran into it as well and decided to do the same…post on the web to save others a bunch of time in trying to figure this issue out. I wish I had found your post a bit sooner 😉 I figured it out on my own and am now commenting on forums to save people time.

    Uninstall IE10. Run sysprep ok.

  10. May 31, 2013 at 9:04 AM

    I got the fatal error dialog when trying to run sysprep and, yes I was running IE10. So I uninstalled the IE10 update which took forever updating my configuration when I restarted. I then checked that I was running IE9. Great I thought, and run the SYSPREP command from the prompt as administrator. It seemed to be running OK as it went on longer than before but then I got the self same “Fatal error while trying to sysprep the machine” dialog pop up. Any ideas where I go from here, as I’d like to move all my user folders to my D drive. I have already moved all the individual Documents, Music, Pictures and so on to the D Drive previously but I still have the original User folder with the App Data and the Program Data on my C drive? I dont particularly want to do a new clean install of Windows, which I know does work when running sysprep as I had to do that on my son’s laptop yesterday after replacing a faulty harddrive. Has anyone had this problem with IE9?

    As of August 19, 2013 or earlier it seems that those entries for IE10 have been fixed in the registry. Possibly a previous hotfix or security patch fixed those entries. Might not be necessary to fix anymore.

    Your solution was spot on many thanks. Contrary to JF’s previous comment, this machine in question was fully patched as of today and needed the registry keys corrected.

    Worked for me replacing for each different string the corresponding values (Cleanup_IE, Generalize_IE, and Specialize_IE)

    Are you sure Sysprep_Generalize_IE has to be replaced with Sysprep_Cleanup_IE?

    I have been having the same problem when I installed windows 7 luxury edition to my USB on my bad but working computer to use for my decent but broken computer and tried to sysprep it. However when I tried this technique I found that the directories which were to be changed from sysWOW64 to system 32 were already system32, I really need help with this as the only way I can fix my broken computer is to prove to the person with the money that except for the hard drive they corrupted with their stupidity, it’s still fine, well that and the screen replacement has also been broken, and the backlight has been dead since we bought it, and that’s my good computer.

    So just to repeat what the problem is, the directories to be changed from sysWOW64 to system32 are already system32.

    Thanks! I came across Sgennadi’s post too, and I was glad to see that you and others confirm it as the solution. As everybody who came across this post knows, by the time you finally get a machine ready for imaging, the last thing you need is a Sysprep error…
    and then I discovered that since Sysprep had already started before it encountered the error, the Administrator account was already disabled (which happens as part of Sysprep in Win7)! Sysprep really should undo that if it encounters an error.

    Thanks to your post I was able to run Sysprep. Hopefully everything will look OK when I start up the image on the target machines.

    Does anybody know if this problem was fixed with IE11?
    If I install IE11, do I still need to apply this manual registry fix before running sysprep?

      Folks, we had the same issue with one of our Master Images and discovered that MSE had been installed and removed during an update of the Image. Re-installing MSE corrected our issue. Longshot that anyone else uses MSE on their base images but there you go.

    Users can choose their systems depending upon the size of the property and requirements desired to
    them. When buying a homesecurity-system, you should always check
    the components of the securitysystem. Most of the
    best modern systems also integrate smart capabilities, which mean that
    the security system is part of an overall home automation system.
