App communities Suddenly cannot access PDF files I suddenly cannot open PDF files that I have saved. I believe this happened after downloading an Adobe Reader update. When I try to open a PDF file I get this message: "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item." However, if I get a PDF file as an e-mail attachment, I can open the file from my email. As an aside, to open a PDF file, I sent it to myself as an attachment and then downloaded and opened it. Also, if I right click on the file and select "Open With" I cannot open with Adobe Acrobat Reader DC but I can open with PDF Vista, whatever that is. Now I'm really in trouble. I got desperate so I uninstalled Adobe Acrobat Reader DC and tried to reload the program from Adobe. It downloads and then goes all the way through the install process and then says Installation failed. "Newer version already installed" And to make matters worse, the PDF Vista program that was on my computer has gone away. At least I was able to use that for a while. I'm running Windows 7 on my HP 520-1047c Update: Yesterday I managed to download and install Adobe Acrobat Reader XI. I can now access my PDF files. My immediate problem has been solved but I still would like to know what the problem is with Reader DC. I must admit I am disappointed that no oe had any suggestions as to how to resolve my problem Hi wildbill1932, Sorry for the delay in response.

Open Adobe Acrobat Reader, go to the "Edit" menu (on Windows) or "Adobe Acrobat Reader" menu (on macOS), and select "Preferences" or "Preferences...". decor Look for relevant settings that might be causing the issue. 2. Update Adobe Acrobat Reader: Ensure that you are using the latest version of Adobe Acrobat Reader. Older versions might have compatibility issues, and updating to the latest version can often resolve such problems. 3. Check File Associations: Make sure that the PDF file type is associated with Adobe Acrobat Reader. To do this: - On Windows: Right-click on a PDF file, choose "Open with," and select "Choose another app." Then, select Adobe Acrobat Reader and check the box that says "Always use this app to open .pdf files." - On macOS: Right-click on a PDF file, choose "Get Info," expand the "Open with" section, and select Adobe Acrobat Reader. Click "Change All..." to ensure all PDFs open with Adobe Acrobat Reader. 4. Clear Cache and Temporary Files: Sometimes, corrupted cache or temporary files can cause issues. Clear the cache and temporary files of Adobe Acrobat Reader to see if that resolves the problem. 5. Check Security Software: Certain security software or antivirus programs may interfere with PDF files. Temporarily disable any security software and see if you can access the PDF files. 6. Test with Other PDF Readers: Try opening the PDF files with alternative PDF readers like Foxit Reader or Sumatra PDF. This will help you determine if the issue is specific to Adobe Acrobat Reader.

7. Restart Your Computer: A simple restart can often resolve unexpected software issues. 8. Reinstall Adobe Acrobat Reader: If the problem persists, consider uninstalling Adobe Acrobat Reader and then reinstalling the latest version from the official Adobe website. 9. Check PDF File Integrity: Verify if the specific PDF files you are trying to open are intact and not corrupted. Try opening other PDF files to see if they open correctly. If none of these steps resolve the issue, it's possible there might be a more complex problem with your system or the PDF files themselves. In such cases, seeking technical support from Adobe or an IT professional might be necessary. Remember to back up any important PDF files before attempting any significant changes to your system.

You may not have appropriate permissions to access the file". I have no idea what changes or would cause this.
