Edwin, No, you may use MsiOpenDatabase, but you need to be careful when and how you use it. For C++, try using PMSIHANDLE. Otherwise for C or other stdcall access, be sure to close the handle in your custom action with MsiCloseHandle. However, it might help to know what you're trying to accomplish at a high level, before commenting on the use this function.
