Quark:
On my Win2kSp4 computer, when I installed Copernic 2 I did it without ever having installed any Copernic version previously (3.x doesn't run on Win2k), and also I run Copernic 2 only occasionally and at the moment it is not loaded, so the following ideas may be completely irrelevant.
Nevertheless, if no one else comes up with better ideas, here goes:
My own guess is that the answer to your question is yes. Therefore I suggest the following:I guess somewhere the first installed version 3 leaves some traces?...preventing version 2 from functioning properly.. could this be the case?
1) I would uninstall whatever Copernic version or versions you now have installed.
2) I would make a complete backup of your registry --- or, even better, a complete backup image of your partition C: (assuming you have the WinXP and your software installations all on partition C: and your data on some other partition such as D:.) But if that's not practical, a registry backup should be adequate.
Your WinXP version of regedit may differ from my XP version (I'd guess that it is), but hopefully the following instructions make sense to you anyway.
While in your Administrator account: Open regedit (start menu, run, type in regedit), select "my computer" in the left (or only) column, then select Edit, Find, make sure that in the "look in" region all three items are checked, and below that region make sure that that "Match whole string only" is NOT checked, then type into the "Find what" field the word "Copernic" (capitalization doesn't matter), and search for Copernic.
Then delete all references to Copernic, regardless whether they are keys, value, or data.
After you get message that says Copernic can't be found, exit regedit, and Reboot.
Log on to each of your Limited User (or any non-administrator accounts), and go through the same regedit routine. (At least in Win2k, even in an Administrator account Regedit doesn't look into non-administrator accounts; you have to look into each one separately.)
After each time you run Regedit, reboot.
Exception: If you have Windows Regclean (or any other registry cleaner with which you are completely comfortable) installed, then after each reboot run that, and let it delete any residue (e.g. class ids {lots of letters and numbers, I think 16 of them} that the registry cleaner finds. Reboot after each time you run the registry cleaner.
Then install Copernic 2.
I'm about to run off for a crucial appointment, so after I get back, later today or early tomorrow I will run Copernic 2 and see if I can find the "indexing disabled" message. I did a Google search for Copernic "indexing disabled" and to my surprise I came up with no hits. You might try some variations, e.g. "index disabled," with and without quotes.
