How to delete system file in WinXp 64bit platform?

Dear Sir,
In WinXP 64bit platform, when I use DeleteFile function to delete
c:\windows\system32\drivers\a.sys ,it can not delete successfully , the
error code is 2(GetLastError ,means can not find the file, but the file is
in the folder),
I guess the system protect the system folder ,then how can I delete the
files in the system folder ?
3ks!

why do you want to delete serial.sys? is it so that your driver can control
the serial ports instead? if so, there are easier ways. Just install your
driver for all the ports on teh machine. Also, change the start type of
serial to disabled via the Service Control Manager (SCM) APIs.

are you trying to overwrite serial.sys? or are you trying to delete
serial.sys as an experiment? What type of user are you when you are trying
to delete the file? You must be an administrator to delete the file. If
all else fails, bring up the directory in explorer, right click on the file
in question and view the security tab. See if your user group is listed.

Dear Sir,
Thanks for your answer!
My user account is administrator,I can delete the .sys file manually in
the system32 folder,but I can not delete the file by call DeleteFile()
function,GetLastError() return value shows it can not find the special
file,but the file exist.
Another method: I can call bat file to delete the .sys file in the
local 64bit PC,but I can not delete the file by using un-install program to
call the bat file.Of course, I compile my setup program in 32bit.
Looking forward to hearing good news!

Cathy

By default you can not perform file operations to the system32 sub-tree
from a 32-bit Windows application. This is because there is a file
system redirector that reflects operations to the WOW64 directory. More
info here:

Dear Sir,
Thanks for your answer!
The method you mention in your mail i have tried before,but
failed, i also tried as follows,failed again:
1. I write the hard code of the path
"c:\windows\system32\drivers\a.sys";
2. I use GetSystemWow64Directory () function get the system
directory,message box shows the path is "c:\windows\sysWow64",i use the
return path +"\drivers\a.sys" in DeleteFile() function;
3. I new a A.txt file in system32 folder,use the above two method
to delete the file;
All above 3 methods,GetLastError() return value shows can not find
the special file.
Any comment is welcome!
Thanks!


Cathy
