Win95 DOS path/file access error??

[RGsail]

I'm running a DOS program on Win95.  I can save the program and all associated files to the harddrive but I can not run it from the HD.  I've changed the location of the folder but that doesn't work either.  I can run the program from the CD drive but when I try to save data colected by the program I get the error;

Error # 67 in 41590
File not valid


I've loaded and run the program on my XP machine without any of the above problems so I'm thinking this is a Win95 issue.

Thanks-

And what program might this be ? ?
