Change
I was just wondering if someone could re-create this code to use winamp 2.x and the winamp 3 reg strings without the "s and the .exe's

ReadRegStr $R0 HKLM "Software\Pure Krypton\Winamp" "Install Location"
ReadRegStr $R1 HKLM "Software\Pure Krypton\Winamp3" "Install Location" 
StrCmp $R0 "" 0 +3 
StrCpy $INSTDIR $R1 
Goto exit 
StrCmp $R1 "" 0 +3 
StrCpy $INSTDIR $R0 
Goto exit 

## $R0 = winamp2 instdir
## $R1 = winamp3 instdir
MessageBox MB_YESNO|MB_ICONQUESTION "Click YES to install into \
your Winamp 2.x directory.$\r$\nClick NO to install into your Winamp 3 directory." IDNO dir2
StrCpy $INSTDIR $R0
Goto exit
dir2:
StrCpy $INSTDIR $R1
exit:
FunctionEnd

How do you mean?

Show me what the read registry values look like.

WINAMP 2: UninstallString "C:\Winamp\UninstWA.exe"
WINAMP 3: UninstallString C:\Winamp3\uninst-wa3.EXE

I wanna use these strings without the .exe's and the " in the strings.
