I'm encountering the same problem as others have reported, i.e. Windows 7 Professional and the following error message when I try to initiate "Set up backup": The backup application could not start due to an internal error. The specified service does not exist as an installed service. (0x80070424) My difference from the others is that I'm not running System Mechanic. I have a new (2 weeks old) Dell Studio XPS laptop with W7 preinstalled. Although I haven't installed System Mechanic, I have run other registry cleaners (i.e. CCleaner, Dell PC TuneUp and Norton Internet Security). Several Dell tech specialists have tried and failed to fix the problem, including several attempts to restore wbengine. Do you have any suggestions as to how I should proceed? Keith

Here are few things I'd like to know before going further. a) Do you remember any changes done on your computer that could have caused this? b) Do you have System Mechanic installed on the computer? From other forum posts, most of the users who have installed this application seemed to be facing similar issue while backing up data in Windows 7. In such case, please refer the thread below which talks about performing registry restore from System Mechanic that seems to have solved the issue. http://social.technet.microsoft.com/Forums/en/w7itprogeneral/thread/55f5fe3a-a1cb-4855-ba4d-73f32c202246 Hope this information helps.

Registry fixers in my opinion are a fools tool and cause far more problems then they fix - do thisThe System File Checker tool To determine whether the issue that you are experiencing is caused by one or more system files that are used by Windows 7, run the System File Checker tool. The System File Checker tool scans system files and replaces incorrect versions of the system files by using the correct versions. To run the System File Checker tool, follow these steps: Click Start then type cmd in the Start Search box. Right-click cmd in the Programs list, and then click Run as administrator. (You must right click the icon to get that option) If you are prompted for an administrator password or confirmation, type your password or click Continue At the command prompt, the following line, and then press ENTER: sfc /scannow When the scan is complete, test to see whether the issue that you are experiencing is resolved. If the issue that you are experiencing is not resolved, use the procedure that is described in the "The System Restore tool" section. The System Restore tool Other troubleshooting methods, such as using the System File Checker tool, may not resolve the issue. If they do not resolve the issue, and the issue that you are experiencing started occurring recently, you can use the System Restore tool. By using this tool, you can restore the computer to an earlier point in time. Using the System Restore tool may not necessarily help you determine the issue. The System Restore tool uses restore points to return system files and settings to an earlier point in time. You can use it to restore the operating system to a point in time in which you did not experience the issue. When you use System Restore to restore the computer to a previous state, programs and updates that you installed are removed.

Thank you for your response. In reply to your questions: a) Do you remember any changes done on your computer that could have caused this? Only the registry cleaners that I mentioned. b) Do you have System Mechanic installed on the computer? NO Regards, Keith

I suspect that backup function related Registry values are corrupt. You may need to use System Restore to restore the system to the status prior to using the Registry cleaner. If it does not help, you may need to do In-place Upgrade to repair the system. It will not remove your personal data and programs. However I still recommend that you save important data before repair. Arthur Xie - MSFT

I note you are using Dell PC TuneUp. I had exactly this problem on a Dell PC I bought last November. If yours is the same problem of wbengine being deleted then try configuring PC TuneUP it ignore that registry entry, like this;Bring up PC TuneUPIn the Tools panel on the LH side select Individual toolsIn the main panel select Repair ProblemsHit start on Repair Registry ProblemsClick on Advanced - Custom Optimisation and Repair and click on NextClick on Next (ignore this panel)On the configure Options panel click on Exclusions and then on AddBrowse to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\wbengine and select it. It is now in the exclusions list. Click next and the registry test will run, carefully avoiding wbengine.Clearly to do this you will need to have re-imported wbengine back into the registry beforehand. This is straightforward to do as noted elsewhere on this site and on the web.Good luckI tried to tell Dell about this problem but failed.Eric
