Have you recently installed any new programs?
The program might be calling a function from the WS2_32.DLL that was added in later versions of windows or was present in earlier versions of windows.
Even though the program may say compatible with windows 2000, it really may not be.
Does the same error occur with other programs using File>Open?
Have you recently installed any plugins into photoshop 6?
Does it happen as soon as you use File>Open?
You could try resetting the photoshop 6 preferences and see if that clears the error
Press and hold down the Shift+Ctrl+Alt keys just after starting the launch of photoshop 6
Keep holding the keys down until you get a dialog asking if you want to delete the adobe photoshop settings file
Thanks for the reply.
I have not installed anything special recently.
As suggested, I tried to reset the software with the key combination "Shift + Ctrl + Alt" without getting any results.
I found out that if you use the OPEN command AS (ALT + CTRL + O) instead of OPEN (CTRL + O) the error disappears ....
Do you get the same error if you go to File>Open without using the keyboard shortcut?
I suppose maybe a reinstall of photoshop 6 is worth a try.
Is that really the ancient Photoshop 6.0.x from well over a decade ago?
