Check if you have tipwin.dll file in MEW root directory. Size should be 52736 bytes and date 03/12/2003. If it is there, there is probably a problem with loading. It can use an OS function which isn’t supported at w95. Sorry, I never tested it at such old Windows version as I didn’t expect anybody would want to use it anymore.
BTW, I thought minimal MEW 9.1 requirement is w98.
