Win7SP1 Unable to install KB5015861

[m3ntal]

Hello,

I'm trying to install KB5015861 on Windows 7 SP1, which is otherwise up to date. This update keeps on failing - as far as I can tell it's due to mstscax.dll missing, but I have no idea how to fix this.

Spoiler: sfc /scannow reports no errors:

sfc /scannow reports no errors:
C:\Windows\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

Spoiler: I ran the SURT/DISM Scan, and tried to install KB5015861, no success.

Hi I'm Gary R,

I'm a Security Analyst, and a Windows Update Trainee, and I'd like to help you with your problems.

As a trainee, any instructions I give you must first be checked by a qualified update expert, before I post them. This will by necessity introduce some delay to any of my replies, so please be patient.

I am looking over your logs now, and will be back as soon as I've finished analysing them.


Please note ... Windows 7 is no longer supported by Microsoft, and as such it may (or may not) be possible for me to source the files we may need to resolve your problem.

Thank you! Much appreciated.

Can you please do the following for me ...

• Navigate to C:\Windows\System32\Config and locate the COMPONENTS file.
• Please copy this file to your desktop.
• Note: If you receive an error that this file is in-use, simply reboot your computer and try again.
• Right-click on this file on your desktop and select Send To...Compressed (zipped) folder. This will create a file named COMPONENTS.ZIP on your desktop.
• The file will likely be too large to upload here so please upload to a file sharing service.
• Examples of services to upload to are WeTransfer and TransferKit and SendFileOnline

Please post me the link to the file

COMPONENTS.zip - thank you!

 

[Gary R]

From some of the entries in the logs you have supplied, and the contents of your Components file, it appears that your copy of Windows 7 is not one that you purchased from Microsoft.

Can you confirm if that is the case, and if not can you please explain how you acquired this OS.

Hi Gary,

The computer was purchased from a local computer shop to support an application that doesn't work on Windows 10. I'll bring this up with them.

Thanks,

OK, I'll leave this topic open for a few days in case you need to get back to me.
