Your life will be a lot easier if you use LogicLib

far easier than using strcpy and jumps

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?

OutFile "Test.exe"



!include "FileFunc.nsh"

!insertmacro GetDrives



Section

	begin:

	StrCpy $R0 ''

	${GetDrives} "CDROM" "GetDrivesCallback"

	StrCmp $R0 '' 0 +2

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
