Windows 10: Installer not opening after UAC prompt

I'm trying to install a piece of software Lumix Webcam if important on a computer and although the same installer works on at least two other PCs, what happens on this particular one is that the UAC prompt pops up, user clicks "Yes", prompt disappears and then literally nothing happens as far as I know.How should I go about diagnosing this, or is there something specific you know could be causing it? I didn't find anything in the Event Viewer, but then again, I don't really know where exactly should I look there.

• Were there any changes made before experiencing this issue?

No, as I posted, I fully updated Windows 10 then went to sleep+work, came back now when it boots and when I open system related things, I am prompted with the UAC Y/N

• What troubleshooting steps have you tried so far?

None so far because the other person thats experiencing this (also on Answers.Microsoft) never got any reply for his/her problem.

• Then type uac, and then click Change User Account Control settings.

  Do one of the following:

  OK. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. You will need to restart your computer for UAC to be turned off.

UAC not allowing software activation

Once again the so called support engineer did not even read the entire thread before posting yet another solution that did not do any good.

However, I was able to solve my situation without your help after all. My original question was how do I turn off UAC. the method suggested in this thread only turns the notifications for UAC off not the UAC itself. In order to turn off UAC completely,
I went into the registry and turned it off there. After doing this, everything installed perfectly.

Here is a link to read about turning off UAC:
