[Can't reinstall plastic]

I was able to restore my original install and then do a proper uninstall.  Then a fresh install fixed it.  Thanks anyway.

 

[Can't reinstall plastic]

I am having a similar issue.  I installed earlier today, but I was having computer issues, so I deleted everything and started over.  Now, when trying to re-install, I am getting the same windows pop-up messages and am unable to install.  All files associated with the earlier install were removed.
