Expected behavior

No error

Observed behavior

I tried upgrading VC 1.26.29 on OFFLINE FullyEncrypted Win10 Version 1909 and here's what I got:

---------------------------
VeraCrypt Setup
---------------------------
Warning: The embedded signature of the Windows Boot Manager used by VeraCrypt (bootmgfw_ms.vc) is still issued by Microsoft Windows Production PCA 2011, although firmware db already contains Windows UEFI CA 2023. Its known CA is currently allowed, but it will no longer start after the PCA 2011 certificate is added to dbx.

Do not apply the PCA 2011 revocation (AvailableUpdates bit 0x80, including combined value 0x280) yet. First complete the Windows 2023 boot-manager update while the VeraCrypt System Favorites service is enabled, then run VeraCrypt Repair/Reinstall so VeraCrypt can import a compatible serviced EFI_EX/EFI copy. Verify the embedded issuer of bootmgfw_ms.vc is Windows UEFI CA 2023 and make sure you have an up-to-date VeraCrypt Rescue Disk.

This check covers only the active Windows boot manager. Before revocation, also verify that decryption fallback and rescue backups are compatible. Creating a new VeraCrypt Rescue Disk can reuse an older stored boot-manager backup; creating the disk alone does not establish that backup's compatibility with the revocation.

OK

What exactly do I need to do?

Connecting to the internet is not allowed so I need to download something from internet on other PC.

Steps to reproduce

  1. Select "Repair/Reinstall" on Setup.exe
