Bypass Windows 7 Extended Security Updates Eligibility

The same has happened to me with Error Code 641 and I have easily solved it by uninstalling BypassESU v7 (both for general Windows updates and for the .NET Framework) and reinstalling it again.

Then I have rebooted the system, deactivated the antivirus and KB4566517 has been installed without problems.

I edit to add that oddly this time when installing the .NET Framework update did not ask me to restart the operating system.

 

As mentioned above, for me, same beginning of the story, but not so happy in the end, since after istalling ByPassESU v7, KB4566517 (NET.Framework) fails now with error 641 (no more 643)

 

Many Windows installation errors are fixed by entering Safe Mode and deleting the SoftwareDistribution subfolder.

The system must be restarted again and new Windows updates are searched for manually and as a general rule the errors disappear. In some occasions, the error code 641 is also produced by the antivirus that we have installed: it is necessary to deactivate it while updating the system. Anyway, read the post immediately above yours where I give a solution to the problem.

 

ndp48-kb4565636-x64_1193b91f484d6834e8c5b7e1d32e8ae69ebec5ae.exe fails with error 643, with/without argument /msioptions "ESU_LOCK=2D40812E-974C-4EA2-8DCC-63C992D505B9".
Waiting for a workaround...

Edit: Solved using BypassESU-v7-AIO, removed NET Framework Bypass, rebooted, reinstalled bypass and than worked.

 

Thats how it works.
Bypass uninstalled, reinstalled, laptop restarted.
Antivirus turned off and then the netframe update worked.

Don't forget to turn on the antivirus.

 

HI there, it should be : /msioptions "ESU_LOCK=2D40812E-974C-4EA2-8DCC-63C992D505B9" , but it does not work for me now. I need help too

 

For me also, it eventually worked.
But since I dislike deactivating Antivirus, after full uninstall / reboot / full install ByPass v7 / Reboot, I tried once more with antivirus active => same error 641
But with Avast deactivated, it woked !

So I'm not sure it was really useful to fully uninstall Bypass then fully reinstall it. I think more that the key point is to deactivate Avast.

But what is important is that at the end, it worked !
Thanks to everybody for advices.... and see you next month !

 

I also use Avast, it's probably because of this.
Then uninstalling and reinstalling the bypass is not required.
....see you next month !

 

You shouldn't have to go into safe mode to delete the software distribution folder. Just make sure Windows Update is stopped and preferably disabled.

Also stop trusted installer from a command prompt:

net stop /y trustedinstaller

 

Thanks. Yes, it doesn't work.

 

Thanks, but it doesn't work.

 

It took awhile, but I finally got all six computers updated. For the first time since the Bypass fun began, I had to more or less go through a different procedure on every machine, although they're essentially all set up the same (four are Lenovo, two are HP).

I won't bore you with the details because I'm sure no one else is in my situation. However, I can say to anyone who's having issues, even though it requires a bit of reading and (for me at least - I'm 73 years old) a lot of concentration, in my experience, if you go through this giant thread, at one point or another, you'll find the solution you're looking for.

As several people have suggested, it would be nice if one of the moderators (are there moderators for this thread?) would go though and get rid of posts - like this one - that really don't contain any hands-on-solution-type information. I won't hold my breath.

Anyway, I'll end this by again thanking everyone who's made it possible for us "little people" to be able to continue using Windows 7. Great job folks!

 

KB4565539(SecOnly), KB4565479(IE), KB4565612(.NET3.5), and KB4565524(RollUp) : Success
KB4565636(.NET4.8) : Failed
It looks like ESUEngine.dll 4.8.4181 ignore "ESU_FLAG" and "ESU_LOCK" arguments.

 

I installed ESU DotNET Bypass and I still had problems with NET framework 4.8 update.
Windows installer was crashing, but after disabling Avast shields everything went fine.
I believe the culprit is a new Ransomware shield.

 

July updates went great !!!!! Thank you folks...Thank you very much !
