Windows 10: Fix 0x80070643 - Error Install Failure when trying to install Windows Update

Microsoft released new security updates for its Windows operating system yesterday. Some administrators see the error message 0x80070643 - ERROR_INSTALL_FAILURE when they try to install the update. The update won't install and trying again throws the same error message again.

Several of our readers ran into the issue. Some received the error message "There were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643)".

The error code 0x80070643 confirms the issue. Microsoft published a support article that confirms the issue and provides some explanation. According to Microsoft, the update is addressing a security vulnerability that could allow attackers to bypass Bitlocker encryption by using the Windows Recovery Environment (WinRE).

The issue that makes Windows PCs throw the error code is that the recovery partition is not large enough to complete the update. Administrators may also get the error message "Windows Recovery Environment servicing failed. (CBS_E_INSUFFICIENT_DISK_SPACE)" when they try to install it.

The only advice that Microsoft offers is to manually resize the recovery partition so that the update can be installed. Note that the instructions work only if the recovery partition is after the OS partition.

One easy way to find out if that is the case is to open Start, type Disk Management and select "Create and format hard disk partitions" from the results. Locate the main Windows drive and check for the Recovery Partition.



If that is the case, you may follow instructions. Please note that it requires shrinking the operating system partition to gain space for the recovery partition.

We recommend that you create a system backup before you make any changes to the system. Microsoft's workaround requires deleting and resizing partitions.



First, check if WinRE is available:

1. Open Start, type CMD, and select "run as administrator" to launch an elevated command prompt window.
2. Run the command reagentc /info. If you see path information, WinRE is enabled. Note the number behind harddisk and partition in the path, these are needed later on.
3. Run reagentc /disable to disable WinRE for the operation.

Now shrink the OS partition to create a new recovery partition:

1. Run diskpart.
2. Run list disk to get a list of all hard disks connected to the computer.
3. To select the operating system disk, run the command sel disk <OS disk index>. Replace >OS disk index" with the harddisk value.
4. List all partitions by running list part. Check for the primary partition there. It is usually the largest.
5. Select the (primary) operating system partition with the command sel part <OS partition index>.
6. Run shrink desired=250 minimum=250. This shrinks the operating system partition by 250 MB.
7. Run sel part <WinRE partition index> to select the recovery partition. Use the partition number that you got when you ran the first command at the top.
8. Delete the partition by running delete partition override.
9. Type list disk again and check if there is an asterisk character (*) in the GPT column of the drive.
   1. If the disk with Windows on it is GPT, run the following commands:
      1. create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
      2. gpt attributes =0x8000000000000001
   2. If the disk is MBR, run the following command:
      1. create partition primary id=27
10. To format the partition, run the command format quick fs=ntfs label=”Windows RE tools”.
11. Run the command list vol to verify that the Recovery Partition is available again.
12. Type exit to exit diskpart.
13. Run reagentc /enable to enable the recovery environment again.
14. Make sure that this is the case by running reagentc /info.

Windows Update multiple Install errors/Failure (error 0x80070643)


Hi All,

I'm wondering if anyone can help.

I have upgraded to windows 10 for a few weeks now and over the last couple of days it has stopped installing any windows updates, the error code that pops up is (error 0x80070643)

It's also stopping me from installing some other programs but not all.

I have tried restarting the computer, Nothing
I've tried restarting wuauserv service, Nothing
I've tried the troubleshooter for windows update, it says problems were found and they were fixed.
I have also cleared the cache for update downloads from the following folder:
C:\Windows\SoftwareDistribution\Download

In the Windows update page it seems to take forever to install the updates and then throws out the following:
There were problems installing some updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:
Security Update for Microsoft ASP.NET MVC 4.0 (KB2993928) - Error 0x80070643
Security Update for Microsoft Silverlight (KB3080333) - Error 0x80070643
Security Update for SQL Server 2008 R2 Service Pack 2 (KB3045313) - Error 0x80070643
Update for Microsoft Visual Studio 2010 Tools for Office Runtime (KB3001652) - Error 0x80070643

Note: this is after clearing the cache in the above folder location.

If anyone can help that will be great as it seems to be affecting installation of other programs.

 

error 0x80070643 (update)

Hey

Try to apply the update manually As suggested by Microsoft. I just wrote a
step by step guide.

However be sure that the update itself is downloaded and that the installation part is failing, and not the downloading part.

Hope it helps you

 

Installation Failure: Windows failed to install the following update with error 0x80070643.

Original Title: Installation Failure: update KB3081704 will not install it keeps failing.

update KB3081704 will not install it keeps failing

this is the error in the event logs

Installation Failure: Windows failed to install the following update with error 0x80070643: Update for Windows 10 for x64-based Systems (KB3081704).

I've ran the update troubleshooter and sfc doesn't fix it KB3081704 keeps failing

I think its something to do with the free dvd player that use to work but hasn't worked since the store update that messed up the start menu and store app.

the bug was later fixed but the dvd player hasn't since then

is there a download or a fix?
