Microsoft Office 2007, throwing errors when opening Thesaurus.

I am geting the following error when I click Thesaurus in Word 2007.

"Microsoft Office Word Can't open the thesaurus. Microsoft office word cannot install the necessary files due to Windows Installer error 1605. This action is only valid for products that are currently installed."

I have uninstalled office 2007 and reinstalled it, I have also installed all components of office 2007 as well. Also after hitting ok about 6 or 7 times the thesaurus pops up.The OS is Windows XP Pro SP2 512mb of RAM if that helps. Looking forward to a response.

Try this out:
To resolve this issue, determine which template causes the issue, and then delete that template from the Word startup folder. To determine which template causes the issue, remove each template from the Word startup folder, and then test by trying to start Word. To do this, follow these steps:
1.      Quit any running programs.
2.      In Windows Explorer, click Folder Options on the Tools menu. Click the View tab, click to select the Show hidden files and folders check box, and then click OK.
3.      Locate the drive:\Documents and Settings\username\Application Data\Microsoft\Word\Startup folder, where drive refers to the drive that Windows is installed on and username refers to your user name.
4.      On the File menu, point to New, and then click Folder.
5.      Type Temp, and then press ENTER.
6.      Click the first template that is listed in the Startup folder, and then move it to the Temp folder.
7.      Try to start Word.
8.      If Word starts successfully, you have removed the conflicting template. If you receive an error message, repeat steps 5 through 7 until Word starts successfully.
9.      After you have determined which template causes the conflict, move all the non-conflicting templates from the Temp folder to the Startup folder.
10.      Click the Temp folder, and then press DELETE.

There are no templates in the startup folder, and there was already a temp folder there with nothing in it.
Then just delete the TEMP folder.
Re-boot your system and try to open the thesaurus again.

This still has not fixed the problem I continue to get the same error when I click on Thesaurus..

      Step 1:
      Open Microsoft Word and begin typing your document. When a word comes up you would like to use the thesaurus for, select it.
      Step 2:
      Choose "Language" from the "Tools" menu and then "Thesaurus." You can also press Shift and the F7 key simultaneously to activate the thesaurus. The thesaurus window pops up.
      Step 3:
      Find the list of word meanings on the left side of the window. These are the possible meanings of the word you selected. Select the meaning that most closely fits how you intended to use the word. For additional help in selecting a meaning, Microsoft Word will put the part of speech of the word in parenthesis. When you have selected your meaning, hit the "Look Up" button.
      Step 4:
      Look on the right side of the window for a list of synonyms generated by the thesaurus. Depending on the word, the thesaurus may also list a few antonyms. These will be displayed with ("Antonym") behind the word.
      Step 5:
      Pick the synonym you'd like to use and hit the "Replace" button. The synonym replaces the original word in your document. If you're unhappy with your list of words, pick the one you like best and hit "Look Up" again. The Microsoft Word thesaurus will then generate synonyms of the synonym.

Tips & Warnings

    * Use the thesaurus by right-clicking on any word in a Microsoft Word document and choosing "Synonyms." A list of potential replacements are listed as well as the option to open up the thesaurus window.
    * Look up additional words in the thesaurus window at any time by typing the word into the text box in the upper right hand corner and hitting "Look Up." Click the "Previous" button to go back to your previous word.

If all else fails then do this:
Re-install your office suite, but look at where it installs it.
When it shows you the folder or destination of where it will be installing the office suite you will need to put in a figure ONE at the end of the line:
C:\Windows\office12\"1" , (without the quotes) and then continue with the install as usual.
Hope all works out.  
Did you have a trial version of Office 2007 installed? If so, you need to use the Control Panel to remove it. (Add/Remove Programs) and then if you have a purchased copy of Office 2007 - then you need to run Diagnostics and Repair it.

In Word, click the Office Button - Big Round button in upper Left Corner
Choose Word Options
Click on the Resources Tab
Choose Run Microsoft Office Diagnostics - Diagnose Button.

Follow the prompts.

Good Luck

I tried both of these options, the diagnostics picked up nothing and office 2007 will not allow me to pick a place to install the files.
Have you tried "custom install"?.
When you re-install it choose "custom install", and try again with answers from the above posts.
