See MS KB258471 - "Error Message: The Following File Is Missing or Corrupted:
C:\Windows\Ifshlp.sys" (http://support.microsoft.com?kbid=258471

VMM32.VXD is a composite file that is built from thirty or more other files
when Win Me is installed and differs from system to system depending upon the
hardware in use.  If you boot to DOS using a floppy can you see if you have
the file vmm32.vxd in your C:\WINDOWS\SYSTEM folder?  If not then you may well
have to reinstall Win Me.  One way you can check whether vmm32.vxd is missing
or not is by typing the following at the A:\> prompt:

A:\>   DIR   C:\WINDOWS\SYSTEM\VMM32.VXD

If present you should see something like:
VMM32    VXD    1,032,968   15/08/00   14:34  VMM32.VXD
(Don't worry about the details, your date and size will most likely be
different)

but if absent you will see:
File Not Found

If the file is still present, and I hope it is, see MS KB258471 (above) which
explains how to proceed to hopefully fix the problem.

Once you've fixed your system you might then want to amend the default
settings for the Registry Checker so that it backs up a copy of vmm32.vxd each
time that it backs up the registry which might save a lot of anguish in
future.  Do this by looking for the file scanreg.ini in your Windows folder
and adding the line
Files=11,vmm32.vxd
beneath the last line of the file.  The Registry Checker will then create a
daily backup copy of vmm32.vxd as well as the registry and the backups are
stored in the rb00?.cab files in the windows\SysBckup folder.  For more
details see MS KB 183603 - "How to Customize Registry Checker Tool Settings"
(http://support.microsoft.com?kbid=183603).
