Windows 95 build 180

Windows 95 4.00.180 is a beta 1 build from 1994-09-09. It was scene leaked in 1994 and mislabeled as build 177, then found again and shared on OSBetaArchive by Overdoze on 2015-12-13. It comes on 14 floppy disks (disk 1 is 1.44MB, others are DMF).

LAYOUT.INF issues
in  on disk 2 is for the 19 1.44MB floppy disk release of this build. This means setup cannot find files in CAB archives it expects, which makes the installation impossible without modifications. One way is to swap the wrong  with a fixed one during installation. To do this:

1. Start the installation as usual and get to the welcome screen, then stop there.

2. You have to save the state of the virtual machine (depends on the hypervisor/emulator you're using) as you can't leave setup to swap.

3. Mount the virtual hard disk (VHD) in Disk Management.

4. Navigate to  and replace   you will find there with the one provided sepparately with the installation disks.

5. Dismount the VHD, then resume the virtual machine.

6. Install the build as usual.

It is important you do this after setup has already copied files it needs from disks 1 and 2 to the hard drive and before it reads  for file locations in CAB archives. Therefore, this is best done at the welcome screen.
