how do i enable full logging?

[jweinraub]

I am trying to do a test on if a file version is set, and that check seems to work (even if the file isn't there) but the action i want it to do, doesn't seem to work.

it does on my system, but not other systems i try it on.

i used the standard event viewing (but normally i turn off output in production), but cant find anything of use.

the loggin from kichik doesnt seem to work for me, when it dumps, it is always blank.

the code in question is:

code:
   ; Install WinPcap

   GetDllVersion "$SYSDIR\Packet.dll" $R0 $R1  

   IntOp $R2 $R0 / 0x00010000

   IntOp $R3 $R0 & 0x0000FFFF

   IntOp $R4 $R1 / 0x00010000

   IntOp $R5 $R1 & 0x0000FFFF

   StrCpy $0 "$R2.$R3.$R4.$R5"

   MessageBox MB_OK $0



  ; 4.0.0.1040

  ${If} $0 == "4.0.0.1040"

  MessageBox MB_OK "We have Packet.dll installed.  Go_on_further"

  Goto go_on_further

  ${Else}

  SetDetailsPrint textonly

  DetailPrint "Installing WinPcap 4.02..."

  SetDetailsPrint none

  MessageBox MB_OK "We do not have it, we will now attempt to install"

  ; enable full logging here to see what is going on here.

  ExecWait `"$EXEDIR\WinpCap\winpcap-nmap-4.02.exe" /S` $R0

  ${EndIf}

  ; End install WinPcap

my the msgbox, i do enter the else clause, but the installer doesn't seem to run at all.

any feedback is appreciated.
