Difference between Path WinSysPath & WinSysPathSysFile?
提问by Peretz
In a .LST file for my VB6 installer there are two lines as follow:
在我的 VB6 安装程序的 .LST 文件中，有如下两行：
[email protected],$(WinSysPathSysFile),......
[email protected],$(WinSysPath),.....
After installing my application, I found out that both go to the same \Windows\System32folder. Do you know what is the difference between both paths?
安装我的应用程序后，我发现两者都转到同一个\Windows\System32文件夹。你知道这两条路有什么区别吗？
Thanks
谢谢

This dates back from VB4, I think, a version that could still generate 16-bit executables. Where the system directory was c:\windows\system, the synonym of $(WinSysPath). $(WinSysPathSysFile) is c:\windows\system32. There should be no difference on a 32-bit operating system, but worth a check. wshom.ocx really does belong in system32. It is already there on any recent operating system.
我认为这可以追溯到 VB4，一个仍然可以生成 16 位可执行文件的版本。其中系统目录是 c:\windows\system，$(WinSysPath) 的同义词。$(WinSysPathSysFile) 是 c:\windows\system32。在 32 位操作系统上应该没有区别，但值得一试。wshom.ocx 确实属于 system32。它已经存在于任何最新的操作系统上。

They both go to the same system folder (The windows folder if it's not writable). The latter just marks it as a system file so it's not uninstalled.
它们都转到同一个系统文件夹（如果不可写，则为 windows 文件夹）。后者只是将其标记为系统文件，因此不会被卸载。
Snippets from Setup1.bas in the PDW:
PDW 中 Setup1.bas 的片段：
fSystem As Boolean 'whether the file is a system file (i.e. should be installed but never removed)
If InStr(strInitialDestDir, gstrWINSYSDESTSYSFILE) Then
sFile.fSystem = True
End If
Case gstrWINSYSDEST, gstrWINSYSDESTSYSFILE
strResolved = gstrWinSysDir
