I downloaded the trial version of Parallels for Mac 4.0. I installed Windows XP Professional without any problems. I also installed Windows 2000 without any problems. I installed Windows 98 Second Edition without any problems, but I can not install the sound drivers and the Parallel Tools for Windows 98 SE. The Parallel Tools installed under XP and 2000 without any problems, but Windows 98 SE will not install the Parallel tools, therefore I am without sound ability under 98. When I click install Parallel tools, the disk drive in Windows 98 says PrlTools [D:/] , but there is no autoplay, and auto notification is turned on in the device manager. I try to update each device with a yellow question mark, there are 5 including the sound, but it simply doesn't do any good. Windows 98 just will not allow me to install the Parallel Tools. Is there any solution to this problem? Thank.
