microstudio wont install error:1612

[farmertom]

i downloaded the new version of microstudio2.4
i tried to uninstall 2.31.5 and nothing happened.i shut down the pc and it was gone.
i then tried to install 2.4 and got the message:
an error occurred during the move data process:-1610
now neither program will install.......same message.
there are no problems with any other programs.
i am running windows 98se.
does anyone have a list of the files and where they are so i can see if there are any that are left behind from the older version
any suggestions would be appreciated
