PRB: Visual J++ Requires a Protected Mode CD-ROM Driver

Windows 95 requires a protected-mode CD-ROM driver to access the Visual J++ 1.0 product. If you use a real-mode CD-ROM driver, the following problems occur:

• Autorun.inf does not execute upon placing the CD in the drive.
• If you try to execute Setup.exe manually by using the Run option on the Start menu, you receive the following error message:
  Cannot find the file "drive letter: \setup.exe" (or one of its components). Make sure the path and file name are correct and that all required libraries are available.
  If your path includes a directory where another Setup.exe resides, this file is found and executed instead.
• If you try to execute Setup.exe manually by double-clicking on the file name in Explorer, you receive the "Program Not Found" dialog box.
  
  If your path includes a directory where another Setup.exe resides, this file is found and executed instead.
• You cannot open certain folders on the CD, and you receive the following error message:
  The folder "drive letter:\foldername" does not exist.
  The following folders cannot be opened:
  • Cab&Sign
  • Cool Tools
  • MSDev
  • Welcome

Windows 95 requires a protected-mode CD-ROM driver to access file names that do not conform to the 8.3 conventions of MS-DOS.

Windows 95 can use a real-mode CD-ROM driver to view the CD; however, it cannot access the files or folders that do not conform to the 8.3 conventions. Real-mode CD-ROM drivers include the following:

• Drivers that must be loaded in the Config.sys file.
• The Microsoft CD-ROM Extensions (MSCDEX) driver (or third-party equivalent) that must be loaded in the Autoexec.bat file.

The Java language uses long file names and lowercase letters as part of its naming convention standards--for example, MySampleApplet.java and MySampleApplet.class. The Visual J++ product, therefore, implements this naming convention, requiring a protected-mode CD-ROM driver in Windows 95.

Some CD-ROM drive manufacturers do not provide protected-mode CD-ROM drivers; therefore, these drives cannot be used with the Visual J++ product.

Using another machine with a protected mode CD-ROM driver in Windows 95 or Windows NT 4.0, use the following steps:

1. Copy the complete Visual J++ CD to a network hard drive and install it over the network.
2. Share out the Visual J++ CD-ROM drive and install over the network.
3. If you are using Windows 95, establish a Direct Cable Connection and install over that connection.
4. If these options are not readily available, installation of a new protected mode CD-ROM driver is necessary. Manufacturers are responsible for providing protected-mode CD-ROM drivers, some of these drivers are available as part of the Windows 95 product.

If a compatible protected-mode CD-ROM driver is not available as part of the Windows 95 product, contact your manufacturer or use an Internet search engine to find a protected mode CD-ROM driver (suggested keywords: "Windows 95 CD-ROM driver," and your manufacturer's name).

For information on this naming convention see the following article in the Microsoft Knowledge Base: For information about protected-mode CD-ROM drive support in Windows 95, please see the following article in the Microsoft Knowledge Base: For information about CD-ROM drives that do not support protected- mode drivers, please see the following article in the Microsoft Knowledge Base and the suggested workarounds section below: For information about using Direct Cable Connection, see Windows 95 Help; search on: "Direct Cable Connection, setting up a direct cable connection"
