Lotus belongs to the IBM company. All the products have been emerged into others. To find out information about this software or alternatives released by IBM, I recommend checking the eCatalog website. Access the website, select your country from the right menu and then you should be able to see exactly what apps are available for your region.
This is the only way to see if the software is available for Windows XP, but since it was released in 1994, I can say that compatibility doesn't exist.
