We have modify your code for kixtart 3.36

code:

---

 ;Look for Adobe, if not installed install it...
 IF (ExistKey("HKEY_LOCAL_MACHINE\SOFTWARE\Adobe") <> 0) ; - software not installed -
       ;Adobe is not present, install it....
       RUN '%comspec% /c "\\Elmo\Common\Software\Applications\Acrobat Reader\rs405eng.exe" '
       SLEEP 20
       $nul=Setfocus("Acrobat Reader 4.05 Setup")
       $nul=Sendkeys("{ENTER} {ENTER}")
       SLEEP 10
       $nul=Sendkeys("{ENTER}")
 ELSE
       ? "Adobe is present.."
 ENDIF

---

Some remarks:

• modify KeyExist to ExistKey.
  
• insert %comspec% /c in your RUN call.
  
• remove GOTO structure.
  
• add $nul= to your function to prevent unnecessary screen output.
  

btw: it was very interesting to see how kixtart 3.63 was handling the unknown
function KeyExist.
