Please be a little clearer...Do you mean that you're now using a Windows XP computer? Did you check to make sure that the Win98 game was compatible with Windows XP?
What type of game? The name of the game might help. Was it a DOS game?
Did you try to download the game again? The error you mention appears to be related to a corrupted installer file.
Hope this helps.
Have finally been talked in to the xp thing. Tried to download a game I had already purchased on the old 98 (which they said I could do). Followed directions exactly-error message - unable to read installer data. Error Log - application mgmt service - specified module could not be found. What the heck is all of this and how to I fix it. Please stay simple and step by step -- I will ALWAYS be a newbie
