Try the Lacerte Tool Hub https://accountants.intuit.com/support/en-us/help-article/system-responses/fix-common-problems-error...

There are printer repair tools.

I did see something on this forum, that I can't find. There was something about Lacerte PDF 4.5 and 6.5 not playing nice together. If the repair tool doesn't work, call support again and ask for someone that knows about these two "pdf printers" and if one or both should be removed.
