when I click on a hyperlink I get "no program is registered to open this file"

Sounds like a file association problem. here are several methods of setting/fixing file associations:

Note: if you have the Click-To-Run installation of Office Starter and you have “normal” installation of other version of Office you have to decide which version is going to have file association. Only one can be invoked by double clicking on file. Normally that would not be Starter.

Try repairing your Office installation, for example via Add or Remove Programs in Control Panel.

Re-register the application

There are several different ways you can reset the proper file associations. Word itself provides a way to do it. Open a command prompt window and, at the command line, enter the following:

Nothing seems to happen when you press Enter, but Word will reregister itself back in Windows. In the process, it resets the file associations for the files it uses, such as DOC and DOT files. You can close the command prompt window and double-click on a document; Word should start right up.

Alternate Re-register the application

Close the app. Open the Run Window: <WIN> R, use the following command (Modify the Path to match your specific installation):

The quotes are necessary, but you may need to change the path so it reflects the location of the winword.exe file on your system. (You can use Windows’ Search tool to locate the path to the winword.exe file.) The /unregserver switch “unhooks” all the references to Word in the Windows Registry.

You should then, immediately, use the following command:

This command causes Word to rewrite all its Registry keys and to reassociate itself with document and template files. Now you can double-click a document file and see if Windows starts Word and opens the document.

Click to Run, CTR, File Association :

* Open File Manager and navigate to the file.

* Right click the file (i.e. doc) and select Properties.

* Now click on the general tab and select open with change.

* Change ''Microsoft Office 2010 Component'' to "Microsoft Office Client Virtualization Handler".

Need to associate the file type with program:

In Windows 7:

1. Right-click the file,

2. Select "Open With"   select [Your Program Here]

3. Check always use this program.

In Windows XP:

1. Locate the file as you have described above

2. Right click the file

3. Select Open with from the pop-up menu

4. Click Choose default program…

5. Select Excel in the Recommended Programs box

6. Check Always use the selected program to open this kind of file

7. Click on OK.

Alternate method of associating file type with program:

·Click Start

·type cmd in the run dialog box then press ok.

·On the command prompt line type "control panel" without the quotation marks.

·In control panel > folder options > file types > new (button) in the new window click advanced.

·In the file extension dialog box type the file extension to fix, ie: exe.

·In the drop down menu locate and select application > click ok.

Sometimes one of these works when you're having trouble with double clicking on the file in windows explorer:
