  • Microsoft Visual Basic 5.0 Learning Edition

This article was previously published under Q173258


When you attempt to install the Learn Visual Basic Now program included with the Microsoft Visual Basic Deluxe Learning Edition, you will receive the following error message:

File Not Found.


The Learn Visual Basic Now CD-ROM contains mixed-case filenames, including Setup.exe. These filenames cannot be read by Microsoft Windows NT 3.5x, or by Windows 95 computers that use MS-DOS CD-ROM drivers.


Contact your CD-ROM drive manufacturer to obtain an updated driver for your CD-ROM drive. For Windows NT 3.5x, the only resolution is to upgrade to Microsoft Windows NT 4.0.


Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.


Microsoft Windows NT 3.5x, Windows 3.1, and MS-DOS cannot read CD-ROM filenames that contain spaces or lowercase letters. However, later versions of Microsoft Windows, including Microsoft Windows 95 and Windows NT 4.0, use updated CD-ROM drivers to allow spaces, lowercase letters, and long filenames.

Because Windows 95 permits extended CD-ROM filenames, it does not have problems reading the CD-ROM for this book. However, Windows 95 configurations that use MS-DOS CD-ROM drivers will not be able to access the extended CD-ROM filenames on this CD-ROM.
