Yeah, don't worry about those errors.
I've refreshed my awareness about this reg cleaner, and I'm afraid it look like there are a lot more bad than good user experiences associated with it.
I use TweakNow, or the reg cleaner in Ccleaner. Both have a reputation for not harming the computer, and both are free or have a fee version. But any reg cleaner can cause problems, if the wrong items are deleted. Where the option exists (and it always should) make sure a backup is made.
The screenshots you took show that there are 24 errors, that they are to do with missing or incorrect file associations, but doesn't show the actual entries. That's OK, leaving that alone is not going to make any difference to the computer performance.
Is this a trial version of Uniblue, that is asking for a payment before it will remove the problems? (Yes or no, I wouldn't "fix" those "problems", not without seeing them.)
Don't go uninstalling this, yet, until we have an idea it has not done any harm. Do you have the feeling it may have done some good, following a registry clean?
Professional opinion is very divided about the need for reg cleaners. It seems a slight majority of the folk who really know about Windows consider them at best a waste of time, and at worst very damaging. Me, I don't know enough. I think I've seen improvements from their use, (sometimes) but I don't strongly recommend them, for the above reason. I've also borked a Windows installation by letting one clean stuff I shouldn't have had cleaned.
The reason you can't pm is because a forum policy was set to prevent spammers - which were a problem, pm-ing everyone with hundreds of spam messages. You can only use PM once you have 20 posts. (Spammers don't last that long, here
. The forum is well and sensibly moderated.)
