PC Compatibility Card: Cannot Write to Floppy Disk on Power Macintosh

I have installed a PC Compatibility Card in a Power Macintosh 4400/200 and cannot format a floppy disk or copy files to a floppy disk in PC mode. Also, the PC Setup icon has the generic look; the unique icon is not displayed. Rebuilding the desktop does not solve th icon problem. I am using PC Setup 1.6. Is the file corrupt? What can be done?

Both of these issues are addressed in PC Setup 1.6.1 (or newer). PC Setup software is available for download from Apple Software Updates sites.

Version 1.6.1 of PC Setup is only supported for use on the Power Macintosh 4400 or Power Macintosh 7220. It has not been qualified for use on other configurations. Newer versions of PC Setup provide more universal support.
