請問一下, 我用 EvID4226Patch 這個軟體去修改 XP SP2 TCP/IP連接數, 但是當卻出現下面的訊息:

===================================
:
:
Do you really want to change the limit to 50?
(Y=Yes / N=No / C=Change limit) Y

Creating work-copy ... done ...
New limit set. Now calculating checksum ...
Checksum is: 0x5F8BF
Patch complete ...
Preparing to install file ...
Installing new file ... failed ...


Error writing to file:
"%SystemRoot%\System32\Drivers\TCPIP.SYS.ORIGINAL"

Patch aborted ...
Press any key to exit ...
================================

結果更新失敗, 請問是這個軟體失效了嗎?
