[Dx4win] 6.03 upgrade problem

[Cal Kutemeier]

I tried to upgrade this evening.  After finishing  the install process using
the suggested prompts, I got the following error message:

PORT DRIVER NOT FOUND!
Check Appendix: files for the correct driver.

I went to one of the pdf help files and found the index.  It mentioned a
file:
   windows\system\vichw11.vxd

I changed my Windows Explorer option to allow me to see hidden files.  I see
vichw11.vxd in the specified directory and in the  PROGRAM
FILES\DX4WIN603\DRIVERS folder.

Now I cannot run version 6.02.

I am running W98 SE on a PII laptop.

Help!
