have a Windows 7 OS . I select Default Programs > Associate a file type or protocol with a program > and then look for the .pdf file extension. It is not there. There is a .pdfx file extension, which I don't really need. I have tried all the methods I could find to add .pdf, but to no avail. For example: I tried right clicking on a .pdf file, selecting Open with, selecting the program (Adobe Acrobat 8.1), checking "Always use the selected program to open this kind of file," and clicking OK. I then go back and look at the list of file extensions and it is still not there. Still .pdfx exists but no .pdf. My problem is getting the .pdf file extension to show up on the file extension list. PDF files do open with Adobe Acrobat, but that is not my concern. I am not wanting just to change the default program for the file type. I want to see the .pdf extension in the list under the Name column. Other PCs (same DELL machine, OS, and MS Office) at my location show it. Mine doesn't. I've spent hours searching for an answer but have not had success. How can I add or delete file extensions from the list?

Anyone know what to do?

Thanks!

First, try this:

Uninstall Adobe Reader (leave Acrobat alone) using Revo Uninstaller, and download the latest version from Adobe's website. Install the new version.

Now see if your pdf's open properly. If they still do not work right, we will have to make registry modifications. But first try installing the latest version of Adobe Reader like I said above. :huh:

Also, open registry editor and see, if you have .pdf class in HKEY_CLASSES_ROOT folder.

That was going to be my next move if reinstalling Adobe Reader did not work: add the registry entries manually (cause it sounds like they aren't there....reinstalling should fix it, though). :huh:

If I can remember correctly I uninstalled Adobe Reader because it keep saying a plug-in was missing, I also uninstalled the Adobe Acrobat. Then I reinstalled Adobe Reader hower when I went to the default programs I could not find .pdf. If this is the case, it sounds like I would need to edit the registry. I will have all the information on this tomorrow, but if I have to edit the registry, (besides backing it up) , is there some sort of batch file that can change the registry for me. The registry scares me, I am afraid of that one false move, that would make me have to reinstall the operating system.

Yes, there is a very simple method for adding things to the registry.

First though, I want you to back up the registry.

In the Start Menu, type regedit and hit Enter.

File > Export > at the bottom where it says "Export range", make sure All is ticked > navigate to the Desktop > type a descriptive name like registryBackup > Save

You can now close the Registry Editor.

Now, open up Notepad, and copy and paste the following information from the Code box into Notepad:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.pdf]
"Content Type"="application/pdf"
@="AcroExch.Document"

[HKEY_CLASSES_ROOT\.pdf\OpenWithList]
@=""

[HKEY_CLASSES_ROOT\.pdf\OpenWithList\AcroRd32.exe]
@=""

[HKEY_CLASSES_ROOT\.pdf\PersistentHandler]
@="{F6594A6D-D57F-4EFD-B2C3-DCD9779E382E}"

[HKEY_CLASSES_ROOT\.pdf\ShellEx]

[HKEY_CLASSES_ROOT\.pdf\ShellEx\{8895b1c6-b41f-4c1c-a562-0d564250836f}]
@="{DC6EFB56-9CFA-464D-8880-44885D7DC193}"

Save this file on the Desktop as pdf.reg (the .reg is important).

Close Notepad.

Minimize all open windows so you can see the Desktop. Double-click pdf.reg and answer "Yes" to the UAC prompt > Yes > OK

The registry keys for pdf files should now be in your system.

You may require a reboot, but try without it first. Any luck? :huh:

Uhh...thanks, I guess. :huh:

I mean, I didn't type that up by hand. I exported my .pdf registry key to a .reg file and simply pasted the contents here. I also cross-checked it against the same key on my netbook to confirm they were the same before giving it to another user to use.

Oh, and please don't call me Mr. or Sir. I'm younger than most of the people on this forum, so it always makes me laugh when people call me Sir or Mr. :huh:

That pdf.reg thing worked like a charm. I uninstalled the adobe reader. The program left in there is adobe.com. Its actually a trial version.
It is saying to create pdf files from your desktop, subcribe. I guess I need the software, not the trial.

Okay, I'm glad the registry fix worked for you. :huh:

As for that program, yes, you have to pay for a pdf creator. You'll still need Adobe Reader to read pdf's, but if you want to make them, you'll have to buy the full version of that program.

Cheers!! :huh:
