The following error message will display when the user specify a drive letter which is either a CDROM or floppy drive on the PC.
if user install j2sdk1.5.0:
"Error 1325: j2sdk1.5.0 is not a valid short file name."
if user install j2re1.5.0:
"Error 1324: The 1324. The path Program Files contains an invalid charater."

Steps to reproduce:
1. Install j2sdk-1_5_0-beta-bin-b14-windows-i586-06_aug_2003.exe. or j2re-1_5_0-beta-bin-b14-windows-i586-06_aug_2003.exe
2. Choose the customize installation.
3. In the textfield that contains <root drive>:/j2sdk1.5.0 or <root drive>:/Program File\Java\j2re1.5.0\ modify the <root drive> to a CDROM or floppy drive letter and proceed.
4. And the error dialog box will display.

It needs a more appropriate error message to express what is the error. For example: "Invalid drive for install"
