English_i386_SolidWorks.Msi not found

I have installed SP0.1 after downloading it. Now SP01.1 hasbeen downloaded and the installation process has started, but isnow asking for English_i386_SolidWorks.Msi on the SP0.1 disk. Ididn't use a disk for installing SP0.1 since I downloaded it, andthat file is not to be found anywhere on the harddisk.
The same happened trying to intall SP01.0 and I gave it up.
Has anyone encountered the same problem or know a way out of this?

Best regards,
