Uninstaller
 

Hi guys,

I'm struggling to uninstall a program. The problem is that it won't delete the file Uninstall.exe neither the install folder.

Here's my code:

code:


;function for check previous version

Function CheckPreviousVersion



  Call KillRunning



  ReadRegStr $R0 HKLM \

  "Software\Microsoft\Windows\CurrentVersion\Uninstall\${PRODUCT}" \

  "UninstallString"

  StrCmp $R0 "" done



  MessageBox MB_OKCANCEL|MB_ICONEXCLAMATION \

  "${PRODUCT} is already installed. $\n$\nClick `OK` to remove the \

  previous version or `Cancel` to cancel this upgrade." \

  IDOK uninst

  Abort



;Run the uninstaller

uninst:

  ClearErrors

  ExecWait '$R0 _?=$INSTDIR' ;Do not copy the uninstaller to a temp file



  IfErrors no_remove_uninstaller

    ;You can either use Delete /REBOOTOK in the uninstaller or add some code

    ;here to remove the uninstaller. Use a registry key to check

    ;whether the user has chosen to uninstall. If you are using an uninstaller

    ;components page, make sure all sections are uninstalled.

  no_remove_uninstaller:



done:



FunctionEnd

Section "Uninstall"

        call un.KillRunning ; close any already running

        

        # Always delete uninstaller first

        Delete $INSTDIR\Uninstall.exe

        

        ;Delete Start Menu Shortcuts

        ;alter to be wildcard - we do not know how many the user chose to install

        Delete "$DESKTOP\Emod Firefox *.lnk"

        ;Delete "$DESKTOP\Emod Chrome *.lnk"



        ;Delete Files & directory

        RMDir /r "$INSTDIR"

        

        ;Delete Uninstaller And Unistall Registry Entries

        DeleteRegKey HKEY_LOCAL_MACHINE "SOFTWARE\${PRODUCT}"

        DeleteRegKey HKEY_LOCAL_MACHINE "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\${PRODUCT}"

        DeleteRegKey HKEY_LOCAL_MACHINE "Software\Microsoft\Windows\CurrentVersion\Uninstall\${PRODUCT}"

Any suggestion?

Thanks in advance!

Does it only happen when you are using _?= with ExecWait or is normal uninstall also broken?

Can you try Process Monitor and see why the delete fails?
