Error 0x8000ffff Windows 10, How to Fix?

The error reportedly occurs during several tasks. Some of them are listed below:

  • Downloading and installing updates with Windows Update
  • Restoring your PC with System Restore
  • Installing a piece of software with InstallShield

Log-In from Administrator Account

A file conflict may arise when replacing system files during the System Restore process. The restore process fails due to failure to overwrite certain system files. Switch the user and log-in from an Administrator user account. Press Windows + X,  select Shutdown or sign out > Sign out, and then log-in on your Administrator account to solve this problem.

Delete Corrupt Registry Entries

The Windows update installation process sometimes fails due to corruption in the Registry. Windows Registry contains the ‘Components’ sub key in the local machine hivey. Delete corrupted Registry entries as instructed:

registry editor
Registry Hivey:


Strings to Delete:

  • AdvancedInstallersNeedResolving
  • PendingXMLIdentifier
  • NextQueueEntryIndex

Remember, a system reboot is required in order to complete the operation.

Caution: Windows Registry is an extremely sensitive system database. It is always recommended that you backup your Registry before making any changes. Your computer may stop working completely if something goes wrong with the Registry configurations. It is therefore recommended that you use automated registry cleaning software such as Intel SOFTWARE Partner Reginout, which automatically resolves issues after backing-up Registry data.

Initiate Required Components

Your computer may have failed to call a required Visual Basic script, which is an essential component of the system. Open Command Prompt as administrator to execute the below commands:

common prompt

For 32 Bit OS: CD %WinDir%\System32

For 64 Bit OS: CD %WinDir%\SysWow64

  • RegSvr32 vbscript.dll
  • Exit

Again, a system reboot is required in order to successfully complete this operation.

Note: If you do not know your system type (32 bit/ 64 bit), open up System dialog by right clicking your ‘This PC’ desktop icon; selecting ‘Properties’. You will get complete information about your hardware and software configurations.

Change Required Service Properties

Open up the Services tool in Windows 10 and scroll down to open Properties dialog of Volume Shadow Copy service. Set the startup type to manual and apply the changes.

Re-register Required DLL Files

One or more DLL files stored on your PC aren’t functioning properly due to corruption in system Registry. Re-registering them might help. In Command Prompt, execute the below commands in sequence:

Delete Conflicting File

If you’re encountering Error 0x8000ffff Windows 10 while installing software using InstallShield, delete the conflicting file named IsProbe.tlb. This file causes conflicts during installation of programs. Locate the following file:

  • C:\Program Files\Common Files\InstallSheild\Professional\Runtime\ISProbe.tlb

You may need to view hidden files & folders in order to delete the above file. To do so, open up ‘File Explorer Options’ dialog through the ‘Search’ feature; and then enable viewing hidden files and folders from View tab.
