Disaster recovery of TFS 2013 to TFS 2018

My TFS 2013 is corrupted. I only have all the .bak files for my collection. While trying to install TFS 2018, in Application Tier I clicked "Configured Installed Feature". I chooses "I have existing databses to use for this Team Foundation Server deployment". I click next till the end. However, I keep getting this error:

TF400711: Error occurred while executing servicing step 'Configure OAuth signing certificate' for component InstallOnPremSTS during ToDev14M80Deployment: Could not find file 'C:\Users\Administrator\AppData\Local\Temp\1\TFSTemp\vctmp7932_199798.exe'. (type TeamFoundationServicingException)

May I know what went wrong? I try to locate the folder, it is indeed doesn't have "vctmp7932_199798.exe". But how to get this exe in the first place?
