Hi,
I'd rather extract the image index#1 to a separate WIM file and discard the original Install.wim.
For example, the multi-edition WIM has this:

I run:
Dism /Export-Image /SourceImageFile:"D:\sources\install.wim" /SourceIndex:1 /DestinationImageFile:"D:\sources\home.wim"
Home.WIM Index
===========
D:\sources>dism /get-imageinfo /imagefile:home.wim

The operation completed successfully.
Now, delete Install.wim from your setup disk. And, rename Home.wim to Install.wim.
