I bet you will find it in your downloads folder. Look for LacerteToolsHub_Setup.exe  My recall is that either Norton or Microsoft said something like "are you really sure you wanna load this yet unknown piece of software?" I said yes, I trust it and it loaded. First time I downloaded I didn't see the warning and I assumed the same thing as you did. 

This my having fun with words tool to hopefully get the fix it tool to you. 

I believe the tool uninstalls Lacerte Tax Pdf driver and re installs it. 

You could try the old pdf repair tool https://proconnect.intuit.com/community/printers/help/pdf-and-component-repair-tools-for-lacerte-and...

The hub tool does the component and pdf repair all in one app.
