The MsiOpenPackage function opens a package to use with the functions that access the product database. The MsiCloseHandle function must be called with the handle when the handle is not needed.

Note  Initialize COM on the same thread before calling the MsiOpenPackage, MsiOpenPackageEx, or MsiOpenProduct function.

Syntax

C++UINT MsiOpenPackage(
  __in   LPCTSTR szPackagePath,
  __out  MSIHANDLE *hProduct
);

Parameters

szPackagePath [in]

The path to the package.

hProduct [out]

A pointer to a variable that receives the product handle.

Return Value

Value	Meaning
ERROR_BAD_CONFIGURATION	The configuration information is corrupt.
ERROR_INSTALL_FAILURE	The product could not be opened.
ERROR_INSTALL_REMOTE_PROHIBITED	Windows Installer does not permit installation from a remote desktop connection.
ERROR_INVALID_PARAMETER	An invalid parameter is passed to the function.
ERROR_SUCCESS	The function completes successfully.

 

If this function fails, it may return a system error code. For more information, see System Error Codes.

Remarks

MsiOpenPackage can accept an opened database handle in the form "#nnnn", where nnnn is the database handle in string form, i.e. #123, instead of a path to the package. This is intended for development tasks such as running validation actions, or for use with database management tools.
