Has anyone the isadmin.dll?
I searched everywhere and can't find it..
I really need it.

also
Is there a registry key that determines that if the current user logged on is an Administrator or not?

Something like e.x.
if the current user is an admin then the key will be 1
if the current user is not an admin the key will be 0

or an environmental variable?

Try the UserInfo plugin which comes with NSIS. There is an example script in the Contrib\UserInfo folder.

There is an undocumented Windows API call for this in the shell32.dll. As part of the Microsoft settlement Microsoft was force to expose a portion of them. One I'm referring to is: ordinal# 680 a.k.a. IsUserAnAdmin.

It exist, I believe, in all NT based platforms. I remember only verifying its existence and it working on NT4 and up.

The bad news is:
It does not contain a function name - only an ordinal#. I believe Microsoft began including the function name in XP, but I don't know if it was always there or introduced in a later service pack.

This is how you would call it in XP using its function name:
System::Call 'shell32::IsUserAnAdmin(v)i .r1'

Unfortunately, I don't believe you can call functions by ordinals using the System.dll plugin - though - I think it would be a nice feature to have included in a future revision to the plugin.

The good news is: You could create your own plugin to call the function via its ordinal yourself.

I hope this was informative if nothing else...

I use the following for validation of Administrator user
(not sure where i got it from)

code:
ClearErrors
	UserInfo::GetName
	IfErrors Win9x
	Pop $0
	UserInfo::GetAccountType
	Pop $1
	StrCmp $0 "Administrator" 0 +3 ;
		Goto done
	StrCmp $1 "Power" 0 +3
		MessageBox MB_OK 'You Must be logged in as Administrator!'
		Quit ;
	StrCmp $1 "User" 0 +3
		MessageBox MB_OK 'You Must be logged in as Administrator!'
		Quit ;
	StrCmp $1 "Guest" 0 +3
		MessageBox MB_OK 'You Must be logged in as Administrator!'
		Quit ;
	MessageBox MB_OK "Unknown error"
	Quit ;

	Win9x:
		# This one means you don't need to care about admin or
		# not admin because Windows 9x doesn't either
		MessageBox MB_OK "Error! This DLL can't run under Windows 9x!"

	done:

fishweasel, you got this from Examples\UserInfo which is the examples folder for the plug-in written exactly for this purpose.
