Are you referring to the Sametime 8 Client, if so the answer is yes. If you get this message you can try the following, uninstall all previous version of Sametime and then try reinstalling the Sametime 8 Client, If this does not work reinstall Notes preferrably 7.0.3 and try the install again. If you have additional problems consult the Lotus Sametime Forum: <a href=”http://www-10.lotus.com/ldd/stforum.nsf”>http://www-10.lotus.com/ldd/stforum.nsf</a>
If you are referring to Sametime 8 or even 7.5.1 on Domino 7, I would not suggest trying to install it because it is not supported. Refer to this link for more details. <a href=”http://www.adamgartenberg.com/gartenberg/agartenberg.nsf/dx/lotus-sametime-and-domino-7.0.3?”>Adam Gartenberg’s Blog</a>Make sure you read the comments section.
