Error 5: Access is Denied While using OSCDIMG to create Winpe x86 ISO with Deployment Tools Command Prompt

Question

Technician computer is Windows 7 HP x64.
Running latest version of WAIK.
Goal: To make a Winpe disc for each processor architecture (AMD64, x86, IA64) with an included Gimage.exe using this code for the default startnet.cmd file found in system32 directory of winpe boot.wim
wpeinit
if /i %PROCESSOR_ARCHITECTURE%==amd64 (
cd x64
start gimagex.exe
if /i %PROCESSOR_ARCHITECTURE%==ia64 (
cd x64
start gimagex.exe
if /i %PROCESSOR_ARCHITECTURE%==x86 (
cd x86
start gimagex.exe
These are the commands I have processed for the x86 variant:
copype x86 c:\pe\x86\
Dism /mount-wim /wimfile:C:\pe\x86\winpe.wim /index:1 /mountdir:C:\mount
**It is at this point I copy over my x86 folder, x64 folder, and overwrite the startnet.cmd file.
dism /unmount-wim /mountdir:C:\mount /commit
oscdimg -n bc:\pe\x86\etfsboot.com c:\pe\x86\iso c:\pe\x86.iso
^^It is at this command I receive this error:
ERROR: Could not delete existing file "c:\pe\x86\iso"
Error 5: Access is denied.
Please note that all commands before were hand-typed, no copy or pasting from any directory or .chm
One thread referred to some Application Management service, but I can report that there is no such service installed in my machine.
Thank You!
UPDATE:
I copied the winpe.wim file from the x86 root directory into the iso directory and renamed it to boot.wim Now, if I copy the contents to a flash drive and put it into a client
computer, it boots to the PE perfectly, script and all.
However, when trying to use the oscdimg command, I do get an .iso successfully, but when I burn it, I don't know what to do in the way of boot options, and if I keep defaults (imgburn)
it results in an un-bootable dvd. 
Suggestions are greatly appreciated.

Don't copy and paste instead type manually it will work.

OMG! Yes, you are correct ... but I have no idea why! I retyped the command line:
oscdimg -n -be:\winpe_amd64\etfsboot.com e:\winpe_amd64\ISO e:\winpe_amd64\winpe_amd64.iso
into Notepad, and then pasted it into the Command Prompt, and it worked!
Perhaps there must be some hidden characters included when pasting directly, even though I first pasted the command line into Notepad, and then into Command Prompt
(C:\Program Files\Windows AIK\Tools\PETools>).
I had to retype the command line in Notepad before copying and pasting, before it would work.
Wow, thanks!
