; Observation: I

get

here when running Win98SE. (Lilla)

; The functions UserInfo.dll looks

for

are there on Win98 too,

; but just don

'

t work. So UserInfo.dll, knowing that admin isn

'

t required

; on Win98, returns admin anyway. (per kichik)

; MessageBox MB_OK

'

User "$R1" is in the Administrators group

'

StrCpy $R0

"

true

"

Goto Done

Continue:

; You should still check

for

an empty

string

because the functions

; UserInfo.dll looks

for

may not be present on Windows

95

. (per kichik)
