Is there a NSIS variable for %ALLUSERSPROFILE%?
If not do you know how I can obtain this environment variable using NSIS code?
Note: If I use ReadEnvStr $R7 "ALLUSERSPROFILE", $R7 contains C:/ProgramData because the installer has requested elevated privileges (RequestExecutionLevel admin). This is sooo frustrating!
Starting with Vista %ALLUSERSPROFILE% is %SystemDrive%\ProgramData. Some of the things that used to be under All Users was moved to %Public% and the rest is in %ProgramData%.
There are several ways to get this directory but they should all give you the same answer:
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}
To expand on @Anders reply, you could also use SHGetSpecialFolderPath and make a simple one line call to receive the path to a folder on the operating system.
System::Call 'shell32::SHGetSpecialFolderPath(i $HWNDPARENT, t .r1, i 0x23, i0)i.r0'
Use it with CSIDL Values, and you can simply call a function and pop the return.
Function ".OnInit"
System::Call 'shell32::SHGetSpecialFolderPath(i $HWNDPARENT, t .r1, i 0x23, i0)i.r0'
pop $1
MessageBox MB_OK|MB_ICONINFORMATION "$1"
FunctionEnd
Section ""
; blank section (so the script runs)
SectionEnd
This will return C:\ProgramData (Vista+) or C:\Documents and Settings\All Users\Application Data (XP) into $1 and display a Message Box showing the path.
By switching up the CSIDL Value (0x23) you can return the path to a bunch of different system folders.
Here are some common CSIDL Values that you can use to return the path:
