note sundialsvc4 <p> To echo the preceding post ... you should always, first, <u>un</u>install what you want to replace, doing it cleanly and with an uninstaller if possible. &nbsp; Then, IMHO, you should reboot the machine. &nbsp; Only <em>now</em> can you feel reasonably confident that nothing is lingering around in memory and so-on. &nbsp; Now, install the new software. &nbsp; If all that you do is to &ldquo;delete the old directory,&rdquo; there is unfortunately an excellent chance that many other critical things are not cleaned-up, <i>e.g.:</i> DLLs in Windows system-directories, and particularly, system registry entries. &nbsp; (Windows, far more than Linux, is <u>ruled</u> by a central database ... the registry. &nbsp; It is both a blessing and a curse.) </p> 1013036 1013036
