That can't be all of your code if you are saying that MsiGetProperty is returning success because you're not checking it in the code. Have you omitted anything? Your VBScript custom action might be ion the same place, but are you positive your C++ is deferred?

We are tying to access the "CustomActionData" propert from C++: #pragma comment(linker, "/EXPORT:modifypackagexml=_modifypackage...@4") extern "C" UINT __stdcall ModifyPackageXml(MSIHANDLE hInstall) { TCHAR szActionData[MAX_PATH] = {0}; DWORD dActionDataLen = MAX_PATH; MsiGetProperty (hInstall, L"CustomActionData", szActionData, &dActionDataLen); MessageBox (NULL, szActionData, _T("Deferred Custom Action"), MB_OK | MB_ICONINFORMATION); } But we get NULL in szActionData, the MsiGetProperty call returns SUCCESS. If we run a VB-script function at the same "place" as the C++ function we can read the property . Does anyone have an idea of what we are doing wrong?
