To Uninstall GEODAS use Windows Add-Remove/Programs. This is found in the Windows Control Panel: Start -> Control Panel. Then Double-Click the Add/Remove Programs icon. Scroll down the list of programs to the GEODAS CD/DVD which you wish to remove and click Add/Remove…
Repeat for as many GEODAS CD/DVDs you have installed. On subsequent GEODAS uninstalls you will get a lot of messages indicating files which cannot be removed because they do not exist. This is because they were removed by the previous GEODAS uninstall.
The GEODAS CD/DVDs share many of the same installed files. Because of this, if you have installed more than one GEODAS CD/DVD, and then uninstalled any of them, you should re-install the GEODAS CD/DVDs that you wish to keep using.
