The argument to MsiDatabaseOpenView should be a handle to a database. That would be there return value of MsiGetActiveDatabase. MsiGetActiveDatabase takes and argument of an installation session which is what the custom action is passed on entry. You've passed and uninitialized database handle to both calls.

I am using a C++ Custom Action and the file is an exe. Any help would greatly be appreciated. MsiGetActiveDatabase(hDatabase); MsiDatabaseOpenView(hDatabase, "SELECT 'Data' FROM 'Binary' WHERE 'Name' = 'Hasp'", phView); MsiRecordReadStream(*phView, 1, szBuffer, &cbBuf); CreateFile(szBuffer, GENERIC_WRITE,FILE_SHARE_WRITE, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); Kind Regards, Natalie Carr ----------------------------------------------------------------------------- - Monitor your physical, virtual and cloud infrastructure from a single web console.
