Error 0x800f0838 when trying to install February Patch Tuesday using .MSU file

[leonsk29]

As the title says, I've downloaded the February 11, 2025 Patch Tuesday update (KB5051987) from the Microsoft Update Catalog and when I run it, it asks me if I want to install it, I click Yes, it says "copying files to cache" or something like that, and then it suddendly throws error 0x800f0838, period.

• The file isn't corrupted, its digital signature is valid,
• I've restarted the PC,
• I've run sfc /scannow,
• I've tried using DISM,

and nothing. Is anyone else having the same issue or is it just me?

Already done that before posting here... none of those solutions work.

and you also have the last checkpoint update KB5043080 in the same directory where KB5051987 resides?

I'm going to try that later today, yes, I also thought about that. Thanks.

Problem solved. I just had to put both .MSU files in the same folder and use DISM to install them. Weird having to use DISM, because double-clicking the file didn't work, same error, but DISM did the work. Thanks, Microsoft.
