Cannot email invoices from quicken

Question

Every time I update to latest version of quicken, I loose my ability to email invoices. I've read every article and comments. I've tried everything. Even tried restorePdfDriver.bat Still cannot email or print using quicken PDF driver. I end up having to use Microsoft Print to PDF on PORTPROMT: then attach to an email. It's really exhausting having to go through this process every time i send an invoice.  Occasionally it comes back when I update latest version, only to go away again. It's really frustrating

After spending time trying to change Quicken PDF printer from NUL to PDF1 port, it said PDF1 port already exist and would not allow me to configure it. I found the PDF1 port assigned to the Driver "Amyuni Document Converter" for the Quicken PDF converter. I was still unable to email invoice from Quicken.
 I then went to download transactions from my financial institutions and noticed an update for Quicken. 
 I downloaded the update and am now able to send an invoice with no problem again. Go figure!

This has been an ongoing issue. I seem to lose my ability to send emails directly from Quicken when I download an update. Then next time I download an update, it comes back again. It's been doing this for about a year now. I guess I'll just have to live with it.
 Thanks for your attempt to help me with this issue.

The port number is PDF1, with a number 1(one) at the end.

I meant to thank you for your responce. I've been having this issue for awhile. Whenever I download the latest update for Quicken, I seem to lose this feature, The feature occasionally comes back when the next update is downloaded. It's kind of back and forth and drives me nuts. I can still send invoices by print to file and then attach to email which is a 3 step process compared to one step.
