Hi! I see that you're having trouble adding a password to a PDF document using PDF Gear. To help you better, could you tell me a bit more about what specifically happens when you try to add the password? For example:

- Are you able to open the PDF in PDF Gear but don’t see the option to add a password?
- Or is there an error message when you attempt to set the password?
- Are you using the desktop app or the online version?
- Also, which version of PDF Gear are you running?

These details will help me guide you more precisely. Meanwhile, here’s a general step-by-step on how to add a password in the PDF Gear app on Windows 10:

1. Open your PDF document in the PDF Gear app.
2. Go to the Tools tab at the top toolbar.
3. Find and click the Password icon (usually labeled something like "Password Protection" or "Add Password").
4. Enter your desired password and confirm it.
5. Save the document to apply the password protection.

If any of these steps don’t match what you see or you encounter an error, please let me know what part doesn’t work, and I’ll help you troubleshoot further. Are you currently able to open and edit other PDFs in the app without issue?

Password is not saving to the document

Thanks for letting me know that the password isn't saving to your PDF document. Let’s try a few things to get this sorted out.

First, I want to confirm a couple of things:
- After you enter and confirm the password in PDF Gear, are you going straight to saving the file?
- When you save, are you using "Save" or "Save As" to create a new file? Sometimes "Save As" helps avoid permissions or overwrite issues.
- Also, is the PDF you’re working on perhaps read-only or opened from a protected location (like a network folder or email attachment)?

Here are some practical steps to try:

1. Use "Save As" instead of Save: After adding a password, choose "Save As" and save the file with a new name on your local desktop or Documents folder. This can help if the original file is locked or restricted.

2. Check File Permissions: Right-click the PDF file in File Explorer, select Properties, and make sure the file is not marked "Read-only." If it is, uncheck that box and apply changes.

3. Run PDF Gear as Administrator: Right-click the PDF Gear app icon and select "Run as administrator." Then open the PDF and set the password again before saving. Sometimes Windows permission settings can interfere with saving changes.

4. Try a Simple PDF: To see if the issue is file-specific, create or download a simple PDF, then try adding a password to it and saving. This will help isolate if the problem is with the app or the original PDF.

5. Update PDF Gear: Ensure you’re running the latest version of PDF Gear as updates might fix bugs around saving password changes.

If these steps don’t work, one workaround some users do is to:
- Open the PDF in a Chrome-based browser (like Edge or Chrome), enter the password to unlock,
- Then select "Print" and choose "Save as PDF" as the destination, which creates a fresh copy with your settings applied.

If you want, I can guide you through that process too! Just let me know.

Are you comfortable trying these steps? Also, feel free to share any error messages or screenshots if something comes up during the process. That’ll help me troubleshoot further!
