Library "File does not have a program associated"

Hi--
whenever I try to open one of my libraries (documents, pictures, videos, or pictures), I receive this message:"This file does not have a program associated with it for performing this action. Please install a program, or, if one is already installed, create an association in the Default Programs control panel." All the default programs seem to be correct; for example, for all .doc files, the default program is Microsoft Word.

If I click on the menu on the left side of the Libraries panel, then the library will open up. I searched through the help forums, and I have attempted every fix I could find.

Sorry that this post is so long, but I figured it made sense to let you know all that I have tried. If there is something else that I haven't tried, could you please let me know? Thanks!

Here's what I've already done to try to fix the problem:

Registry Booster
-------------------------------------
And Merging library-ms - Library folder.
lnk - Shortcut link (LNK) files.
this way: To Fix Using a REG File Download
1. Click on the Download button below to download the file below.
Fix_Manage_Error.reg
[IMG]file:///C:/Users/Dennise/AppData/Local/Temp/msohtmlclip1/01/clip_image002.gif[/IMG]
2. Click on Save, and save the .reg file to the desktop.

3. Right click the downloaded .reg file on the Desktop and click on Merge.

4. Click on Run, Yes, Yes, and OK when prompted.

5. When done, you can delete the downloaded .reg file if you would like to.

If your still get an error afterwards, then download and merge the lnk (LNK) option in the tutorial below to restore all of the default association for shortcuts (lnk), and try again.

-----------------------------------------
I tried this:
1. Open the Start Menu, and type regedit in the search box and press enter.

2. If prompted by UAC, then click on Yes (if administrator) or enter the administrator's password (if standard user).

3. In regedit, navigate to the location below.
HKEY_CLASSES_ROOT\lnkfile
4. In the right pane of inkfile, right click on a empty space and click on New and String Value. (see screenshot below)
-----------------------------------------
and this:
Download ShellExView (from nirsoft.net) and run it. It will scan the registry for all the shell extensions. Once the scan is over and the list is displayed, you need to spot the context menu handlers. Sort the results using "Type", so that the context menu handlers are displayed together.

The rule is to disable non-Microsoft context menu handlers *one-by-one* and verify if the problem is solved. If disabling one does not solve the problem, undo the disabled item and disable the next non-Microsoft handler. Do the same until the problem is solved and finally identify the culprit. Scroll right to see the Company Name column in ShellExView.

and this:
Restore Default Windows 7 File Extension Type Associations:
Default File Type Associations - Restore

Jonathan,

Thanks for your response. Yes, I did attempt "restore default libraries," but that didn't work. I did as you suggested, and ran "SFC /Scannow" in an administration-level command prompt, and got the response "no integrity violations." I tried to run the "LibraryFix_Win7.reg," but every time I do I receive this message: "Cannot Import C:\Users\[my name]\Downloads\LibraryFix_Win7.reg: Not all date was successfully written to the registry. Some keys are open by the system or other processes."

I restarted my computer (as it rebooted, I get a message saying that one of the disks needed to be checked for consistency--after the CHKDSK, however, no errors were found), and tried the LibraryFix again, but got the same error message. Is there a specific process I should end in order to be able to run the LibraryFix? I don't want to end the wrong process by accident.

Thanks again for your help.

Jonathan--I will try to run the file in safe mode and see what happens.--Thanks.

Shawn--I did a system restore a week ago; it's only after the system restore that I started having this problem (I've never had it before, ever, so not sure that the system restore had anything to do with it...just coincidence?) Should I try system restore anyway, even though the issue wasn't present a week ago?

Thanks for your suggestions.

Shawn,
I tried a system restore, but it didn't work; I tried again, this time from about a month ago, and this time it worked. I still don't know what the problem was, but at least my libraries work correctly again.

Thanks for your help.

Aye Carumba!
Reinstall? Now I'm really glad this worked! I'm a student and this has already eaten up so much of my time.

Thanks for all the help.
