    Program Can't Start Because Combase.dll is Missing...


    Solved Edit: Did not find a fix and performed clean install by wiping drive and recovering from backup.

    Currently cannot run any .exe [Edit: I can run certain programs examples below], trying to do so will prompt the message "The program can't start because C:WINDOWS\SYSTEM32\combase.dll is missing from your computer. Try reinstalling the program to fix this problem."

    I have tried sfc /scannow and it claims to "find and successfully repair" corrupted files but the problem persist. The log file created by the scan states that it cannot repair because combase.dll is missing and cannot regenerate the file because it is missing. It appears to copy it from backup but then states the source file in store is also corrupt.

    My OS is Windows 10 64 bit. The last changes made to the system were automated windows updates. I've also tried system restore points but they fail to restore, system resets also fail at about 38% completion. I can't use my Windows 10 install USB to repair because the setup won't start unless I boot from it. I've also tried all of the above in safe mode. What troubleshooting steps can I try?

    Hi oddparity and welcome to Tenforums.

    If you can run the sfc command, then you should be able to run the DISM command. Using DISM, you can specify a Windows image to use to replace the missing file. Basically, you download the W10 ISO, then run the command pointing to it. See the tutorial here:
    DISM - Repair Windows 10 Image - Windows 10 Forums

    You could try this command first, (at an admin command prompt), and if it gives an error, grab a W10 ISO and try the second command below:
    Dism /Online /Cleanup-Image /RestoreHealth

    Download the ISO from MSTechBench, right-click and select MOUNT, which will give you a new drive letter for the ISO, and a wim file, then run the command
    Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:D:\sources\install.wim:1 /limitaccess

    Replace D:\sources\install.wim with the actual location of your wim file in your downloaded and mounted ISO.

    Hope that helps!

    Do you have any older versions of MS Office installed?

    This might shed some light on the issue - not sure.

    Thank you for your reply,

    [Step 3]
    Code:
    Dism /Online /Cleanup-image /Checkhealth
    This returns no component store corruption detected.

    [Step 4]
    Code:
    Dism /Online /Cleanup-Image /ScanHealth
    This line returns: Error 1726 at 20% completion for image version 10.0.10586.0

    [Step 5]
    I am currently downloading the W10 ISO to complete step 6 in the provided tutorial I'll post a new reply when completed.

    No, I actually don't have any version of MS office installed currently.

    Ok, I downloaded the ISO image for Win 10 x64 and mounted it to drive E:/

    I proceeded with [Step 6] and ran the following line on an elevated command prompt.

    Code:
    Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:E:\sources\install.wim:1
    The result for the above line was Error: 1726 remote procedure call failed at 20% completion.

    Code:
    Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:E:\sources\install.wim:1 /limitaccess
    The result for the above line was the same.

    Please try running this command in an elevated command prompt:
    Dism /online /Cleanup-Image /StartComponentCleanup
    We may need to have a look at your dism log - let me do a little research on this.

    Here you go: sfcdetails.txt

    Also, I can use Microsoft Edge, Maps, Mail, OneNote, Xbox and ITunes almost every other program I try for example [Chrome, Firefox, Steam, Discord, Norton, GeForce Experience] gives me the error however.
