Well I tried, I uninstalled all VC Redist, then reinstalled only the ones needed (2010 and 2015). I even installed a newer version thinking it would over write mscore. And I tried to uninstall .NET, but from everything I've read, but after Windows 10, there isn't a way to do that. I do have .NET 4.6.2 installed so installing .NET 4.6.0 as required isn't possible anymore. Deleted and then reinstalled LSPDFR, but after everything, still nothing. I keep getting the same error message.
