IF EXIST在Windows批处理中的C:\ Windows \ System32中的文件上的错误行为(Inno Setup) [英] Wrong behavior of IF EXIST on a file in C:\Windows\System32 in Windows batch (Inno Setup)

问题描述

我正在尝试通过Inno Setup使用批处理脚本复制一个Windows .dll文件.

I'm trying to copy one Windows .dll file by using a batch script through Inno Setup.

显然，即使C:\Windows\System32中没有msvcr120.dll文件(我可以确认)，我也只能看到文件存在" . 当然，我也尝试删除下面的双引号.

Apparently, even though there is no msvcr120.dll file in C:\Windows\System32 (I can confirm) I can only see "file exists". Of course, I also tried to remove double quotation below.

if exist "C:\Windows\System32\msvcr120.dll" (
    rem file exists
    echo  "file exists"
    pause
) else (
    rem file doesn't exist
    copy %1\Utilities\msvcr120.dll  C:\Windows\System32\msvcr120.dll
    echo  "file doesn't exist"
    pause
)   

我手动检查了

C:\Users\changwon>dir /A:HS C:\Windows\System32\msvcr120.dll
 Volume in drive C has no label.
 Volume Serial Number is 4A80-BDED

 Directory of C:\Windows\System32

File Not Found

你能告诉我哪里出问题了吗?

Can you tell me what is wrong?

[Run]

Filename: "{app}\bin\Icacls\cacls.bat"; Parameters: """{app}"""
Filename: "{app}\Install\psql_init.bat"; Parameters: """{app}"""

其他结果

C:\Users\changwon>dir /A:L C:\Windows\System32\msvcr120.dll
 Directory of C:\Windows\System32

File Not Found

C:\Users\changwon>where msvcr120.dll
INFO: Could not find files for the given pattern(s).

更新

Windows 7 64位，在C:\ Windows \ SysWOW64中有一个msvcr120.dll. 但是我正在尝试将文件从源目录复制到C:\ Windows \ System32.

UPDATE

Windows 7 64bit and there is a msvcr120.dll in C:\Windows\SysWOW64 instead. But I'm trying to copy the file from my source dir to C:\Windows\System32.

推荐答案

该文件可能存在于C:\Windows\SysWOW64中.

Inno Setup是32位应用程序.因此，默认情况下，要运行批处理文件，它将执行32位的cmd.exe.

Inno Setup is a 32-bit application. So by default, to run a batch file, it executes the 32-bit cmd.exe.

查询C:\Windows\System32时的32位cmd.exe，被重定向到C:\Windows\SysWOW64.

了解有关有关32位和64位安装的问题

如果使用[Run]部分中的条目运行批处理文件，请使用 64bit标志强制执行64位cmd.exe:

If you are running the batch file using an entry in the [Run] section, use the 64bit flag to force execution of the 64-bit cmd.exe:

[Run]
Filename: "{app}\bin\Icacls\cacls.bat"; Parameters: """{app}"""; Flags: 64bit
Filename: "{app}\Install\psql_init.bat"; Parameters: """{app}"""; Flags: 64bit

---

尽管它是32位DLL，但实际上您希望在C:\Windows\SysWOW64中使用它.

---

Though if it is a 32-bit DLL, you actually want it in the C:\Windows\SysWOW64.
