For the last year, my laptop has refused to install Win11 24H2. It would hang and revert in the background without installing. With Win11 25H2 available and also failing, I decided to finally fix this.
Sometimes there was an error code 0xC1900104 which means it timed out.
Searching around, there are suggestions to remove drivers, download the ISO to install instead, and do Windows Update repair.
I narrowed it down to the Sennheiser Audio driver by looking at setupacct.log in C:\$WINDOWS.~BT\Sources\Panther. That driver was listed as the last item before it hung and reverted.
After uninstalling the Sennheiser Audio driver, install proceeded as expected. And I've not added the driver back.
What's the odds I remember this a year from now when 26H2 is released?
Incredible! - For ages I have been searching high and low on how to fix this issue and error. Multiple times I've tried many different techniques, playing in CMD and editing god knows what else.
ReplyDeleteI've stumbled across this page via a google search and voila! It's fixed my issue. Sennheiser Audio Driver being the blocker at 61%. After an uninstall, it's now managed to install Win11 25H2. After a few other lingering updates, and a few restarts. All is well and a reinstall of S.A.D has been completed.
