Check installer has admin rights or not?
Hi!

Is there way to get information about installer has administration rights or not?

Problem:
When I try to install program to "Program Files" folder on Windows Vista the following error is shown "Cannot open file for writing: C:\Program Files\program.exe". I dont want my users get such messages. I want they get my message like "You should install program to another folder or run installer with admin rights". What can I do?

The better solution is to check if installer can run with administration run then do it, otherwise notify user about insufficient rights. Is that possible?

Use the included header MultiUser.nsh

I do it like this:

!macro CheckUserRights
  !define ID ${__LINE__}
  ClearErrors
  
  UserInfo::GetName
  IfErrors Win9x_${ID}
  Pop $0
  UserInfo::GetAccountType
  Pop $1
  
  StrCmp $1 "Admin" Win9x_${ID}
  StrCmp $1 "Power" Win9x_${ID}
  
  MessageBox MB_OK|MB_ICONSTOP|MB_TOPMOST "$0, you don't have the required access rights to install this!"
  Quit
  
  Win9x_${ID}:
  !undef ID
!macroend

Function .onInit
  !insertmacro CheckUserRights
FunctionEnd
