Description
This is an extension to Uninstalling a previous MSI (Windows installer package). It's another version to remove an installed MSI product. I wrote a simple function and a few symbols:
How To Use
What you need is the ProductID (ProductCode) of your previous MSI installation. Send it onto the stack and call the function
Push "{48E5A72D-whatever-xxxx}" call CallMsiDeinstaller
The Function
!define OLDVERSIONWARNING \ "Old version found. Do U want to remove it?" !define OLDVERSIONREMOVEERROR \ "There was a problem removing the software ... Sorry" !define INSTALLSTATE_DEFAULT "5" !define INSTALLLEVEL_MAXIMUM "0xFFFF" !define INSTALLSTATE_ABSENT "2" !define ERROR_SUCCESS "0" Function CallMsiDeinstaller Pop $R0 System::Call "msi::MsiQueryProductStateA(t '$R0') i.r0" StrCmp $0 "${INSTALLSTATE_DEFAULT}" 0 Done MessageBox MB_YESNO|MB_ICONQUESTION "${OLDVERSIONWARNING}" \ IDNO BreakMe System::Call "msi::MsiConfigureProductA(t '$R0', \ i ${INSTALLLEVEL_MAXIMUM}, i ${INSTALLSTATE_ABSENT}) i.r0" StrCmp $0 ${ERROR_SUCCESS} Done MessageBox MB_OK|MB_ICONEXCLAMATION \ "${OLDVERSIONREMOVEERROR}" BreakMe: Abort Done: FunctionEnd
