Your life will be a lot easier if you use LogicLib

far easier than using strcpy and jumps

ok figured it out i think but this is what i got

Function CHECK
        
      
        ${If} ${FileExists} "$9\EXAMPLE.exe" 
        StrCpy $R0 "$9" ;$R0 contains the drive you're looking
        StrCpy $0 "StopGetDrives"
        next:
        Push $0

        ${Else}
        MessageBox MB_OK "Please Insert EXAMPLE Disk"
       
        
        
FunctionEnd

and this is what i get when it's done with the creation

Processed 1 file, writing output:
Adding plug-ins initializing function... Done!
Error: could not resolve label "_LogicLib_Label_2" in function "CHECK"
Error - aborting creation process

anyideas why it's not workin?

and is there ne way for it to check again after you press ok?

missed the EndIf:

Function CHECK
        ${If} ${FileExists} "$9\EXAMPLE.exe" 
        StrCpy $R0 "$9" ;$R0 contains the drive you're looking
        StrCpy $0 "StopGetDrives"
        next:
        Push $0

        ${Else}
        MessageBox MB_OK "Please Insert EXAMPLE Disk"
       
        ${EndIf}        
FunctionEnd
