Greetings! @MyINT24. 

I can see how the error pop-ups affect your experience when navigating QuickBooks Desktop (QBDT). I appreciate you for performing some troubleshooting steps to rectify the issue. As your assistant, I am committed to helping you overcome this issue so that you can have a seamless experience with the program.

It can happen during printing, emailing, or saving a PDF in QuickBooks Desktop. To resolve the issue, let’s perform the recommended solutions below:

1. In the QuickBooks Tool Hub, select Program Problems.
2. Download and run the QuickBooks Print and PDF Repair Tool.
3. Once the tool completes, try the .pdf file-related task that originally generated the error.

Then, proceed with restarting and resetting your temp folder permissions to isolate the issue. Here's how:

1. Press the Windows key + R to open the RUN command.
2. Type %TEMP% and press Enter.
3. Right-click an empty area of the temp folder and choose Properties.
4. Click the Security tab.
5. Ensure all usernames and groups are showing on the Security tab have Full Control.
6. Try saving as PDF again within QuickBooks once permissions have been set to Full Control.

Lastly, confirm you can print to your XPS (only for Save as PDF and Email issues). QuickBooks uses parts of the XPS Document Writer to save as PDF.

1. Open Notepad and type something on it.
2. Go to File, then select Print.
3. Choose the XPS Document Writer and click Print.
4. Select your Desktop in the save as dialogue box.
5. Navigate to your desktop and see if you can view the XPS document you printed from Notepad.
