I tell you what happened:
I’ve been in touch since somewhere in the end of December 2007 with the team of IBM China, responsible for the development of IBM new and free Office Suite: Lotus Symphony. The release in question was a beta 3, supposed stable. No reason it wouldn’t be as beta 1 and 2 were already stable. My issue was that every time I tried to install it, for some unknown reason the process was aborted with an error message: “partial install” occurred. I went through everything from deactivating all security software, including CFP 3, AVAST, Windows Defender…to changing the temporary folder location, deleting all files and registry entries left after failed Lotus Symphony installs…and nothing changed, no way to install it. And the development team, although some other users (who didn’t say if they used CFP) had the same issue, just couldn’t reproduce the issue (on Windows XP).
And this morning, I got another mail from IBM China so I thought why not try that: instead of just deactivating CFP I will uninstall it completely, reboot, and see what that does. And guess what: no problem anymore, Lotus Symphony would install like a breeze. Which means in other words that even deactivated, Def+ or the firewall or both still have some impact on the system, even after reboot.
Last thing is I felt obliged to send a new mail to IBM China to tell them I was sorry about all the trouble and the time they spent investigating and trying to reproduce the issue, when the fault was somewhere else.
(Wanted to add that as I successfully installed Lotus Symphony, with CFP not present in the system, I noticed a prompt from Windows Firewall to unblock a connection from Lotus Expeditor. Windows firewall, as you know, prompts to unblock without blocking anything by default, where CFP fortunately blocks until permission is granted. Could have been that blocking the install with CFP present (but inactive), but I never found anything in the logs of CFP when the Lotus installs failed.
You know sometimes, I wouldn’t say Comodo rocks that much… (:WIN), but hey, now that Lotus Symphony is well installed on my PC, I’ve already reinstalled CFP :SMLR
