ERROR_INSTALL_TRANSFORM_FAILURE 1624 There was an error applying transforms

ERROR_INSTALL_TRANSFORM_FAILURE 1624 There was an error applying transforms. Verify that the specified transform paths are valid.
I have an install, generated with InstallShield for Windows Installer 1.1. Everything runs well. But now I have two clients with a problem ERROR_INSTALL_TRANSFORM_FAILURE (1624) when I call MsiOpenPackage from a C-Library.
I have not found any information about this error and how to fix it. Please help me.
