获取%ALLUSERSPROFILE%的NSIS变量

Question

有NSIS变量%ALLUSERSPROFILE%吗？

如果不是,您是否知道如何使用NSIS代码获取此环境变量？

注意:如果我使用ReadEnvStr $R7 "ALLUSERSPROFILE",则$R7包含C:/ProgramData因为安装程序已请求提升权限(RequestExecutionLevel admin).这太令人沮丧了!

从Vista%ALLUSERSPROFILE%开始是%SystemDrive%\ ProgramData.以前在"所有用户"下的某些内容已移至%Public%,其余内容在%ProgramData%中.

有几种方法可以获得这个目录,但他们都应该给你相同的答案:

ReadEnvStr $0 "ALLUSERSPROFILE"
DetailPrint %ALLUSERSPROFILE%=$0


System::Call 'userenv::GetAllUsersProfileDirectory(t.r0,*i${NSIS_MAX_STRLEN})i.r1'
DetailPrint GetAllUsersProfileDirectory=$0


; In Vista+ %ALLUSERSPROFIL% and CSIDL_COMMON_APPDATA is the same directory:
SetShellVarContext all
DetailPrint All:Appdata=$AppData


!define FOLDERID_ProgramData {62AB5D82-FDC1-4DC3-A9DD-070D1D495D97}
System::Call 'shell32::SHGetKnownFolderIDList(g"${FOLDERID_ProgramData}", i0x1000, i0, *i.r1)i.r0'
${If} $0 == 0
    System::Call 'shell32::SHGetPathFromIDList(ir1,t.r0)'
    System::Call 'ole32::CoTaskMemFree(ir1)'
    DetailPrint SHGetKnownFolderIDList=$0
${EndIf}
