Trying to install parallel tools - nothing happens

Last week my mouse suddenly stopped working in windows, I was able to use online help files to sort of fix that, but I used to be able to use the mouse across mac and windows seemlessly, now I have to constantly ctrl-alt out of windows. I read that this could be a problem with parallel tools (or I need to upgrade). So I uninstalled parallel tools and now I cannot reinstall it.

When I click action-> install parallel tools absolutely nothing happens - though if I go back up to action I have the option to cancel the non-happening installation. I have tried restarting both the virtual machine and my mac. I tried going to edit-> virtual machine and changing the cd-rom from 0:1 to 1:1 as I read on another forum, that also did not work.

Please understand that I am not so familiar with all the computer workings - though I am trying. I know that is not so welcome in these types of forums sometimes - but while I truly appreciate any help at all you can try and offer, please try to make it idiot friendly.

Thanks so much.
