Re: 3rd party updates failing to install with error 0x800b0004(2146762748)
Please login to your WSUS server and check the below configuration.
- Run the MMC > Snap-in certificate > computer
- Check the WSUS folder if it contains the private key of the code signing certificate. If this doesn't have a private key or just a public key, then delete the certificate from WSUS.
- Login to the IE as an administrator ( Right-click run as admin) and open SVM.
- Go to Patching WSUS/ system center and try to create an install certificate, if you receive an error while creating a certificate then follow the below steps.
- Microsoft has disabled the feature enabling the creation of a WSUS self-signed certificate on Server 2012 R2.
While Server 2012, 2012R2, 2016 - WSUS will not generate self-signed certificates by default, it is possible to restore the legacy behavior by setting the following registry key:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Update Services\Server\Setup\
- Create DWORD value: EnableSelfSignedCertificates = 1
- Try to create a certificate again.
- If you do have the private key of the code signing certificate in the WSUS folder then check the pubic key of that certificate in trusted root and trusted publishers.
- After checking all the things, Please try to create a package and publish it to your WSUS server.
We hope this will resolve your issue.
