Need review of .bat for running old software on Win7 (64)

Im try to run an older version of Photoshop (I have the license to this one) but explore is locking me out. I have run similar bats for playing older cd based games - this is my first time trying it as an only harddrive based file. I just want explorer to go away when I start the program and return when I close the program.

The "exe" I want to runs is within:
Drive= c:\
folder = software
sub folder = Photoshop 5.5
exe name = Photoshp.exe

Code as I have it:

TASKKILL /F /IM "explorer.exe"
start /w C:\"Software"\Photoshop 5.5\Photoshp.exe
start C:\Windows\explorer.exe

Saved as = PH55.bat

If I could get some feed back before I run it and other ideas I could use to help. Thank You!
