[SOLVED] The referenced assembly could not be found.

[swstrath]

When attempting to install a feature on Server 2016 I am presented with the error "The Referenced assembly could not be found. Error: 0x80073701"

When running dism, the following 1015 event is logged in the even viewer "0 of 18 instances of system store corruption have been repaired. Unrepaired corruptions may lead to failures in future system servicing."

I have tried using dism with a different sources but its not fixed it.

Can anyone help fix this issue?

Great, here's the next fix.

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

I have attached requested logs but I retried the Install and its now Successful so looks like my initial problem has been solved. I did receive an error when running dism so not sure if that still indicates a corruption somewhere, its not really hindering me though at this point.

 

[Maxstar]

Glad the installation of the feature succeeded without any issues. Can you please reboot the server and then run DISM again.

 

[swstrath]

Hi Maxstar, That restart seems to have done it. Thanks for your time and help, I really appreciate it.

 

[Maxstar]

Hi,

You're welcome. Glad everything is up and running again...
