Open .pdf file in Word & "Convert File" Box appears...Weird.

Question

Using my MacBook Pro, I click on a PDF file to open in Microsoft Word & an angry box appears that says "Convert File."
In the box it says: Convert file from: then it lists various file types i.e., Text only, MS-DOS Text, Rich Text Format, HTML Document, Single File Web Page, Unicode Text and many more.
It is trying to open a PDF file in Microsoft Word.
I can't figure out how to change so it opens!!!
I made the fancy document myself in Microsoft Word and saved it in PDF format on the same computer.
I am a new Mac user....so if you tell me to go somewhere (well, not anywhere..on the computer!); please be specific and help me get there!
I've tried the right click trick, open with trick...no luck.  That's not even an option!
This kindergarten teacher THANKs YOU oh so much!

Answer 1

I found this...But I don't understand it.   I downloaded the latest versions...still can't view the PDF.
Am I doing something wrong?  I don't want to edit it!  I just want to VIEW IT~!
Overview
Adobe Reader plug-in and Acrobat plug-ins before version 10.1.3 are incompatible with the Safari 5.1 browser that shipped with Mac OS X 10.7 and for 10.6. The Adobe Reader and Acrobat stand-alone applications are unaffected and Safari 5.1 renders PDF documents natively. However, the Adobe Reader and Acrobat browser plug-ins before 10.1.3 don't function as expected in LiveCycle and Acrobat workflows that require either plug-in to render PDF documents in Safari 5.1.

Affected customers
Any Adobe Reader, Acrobat, and LiveCycle customers who require the Adobe Reader or Acrobat plug-in to render PDF documents in a browser when only Safari 5.1 is present.

Workarounds
Options include the following:
Continue to use Safari 5.0.x and Mac OS X 10.6.
Upgrade to Adobe Reader or Acrobat version 10.1.3 or later.
Save the PDF file from Safari to the computer, and then open it directly in Adobe Reader or Acrobat. 
Use desktop virtualization technology such as Citrix to allow applications to run in a controlled environment where the Safari browser isn't upgraded to version 5.1.

Can customers use a different web browser like Chrome or Opera?
Acrobat Reader plug-in and Acrobat plug-in are dependent on the WebKit WebPlugin API and capabilities that are unique to Safari. Other browsers like Chrome or Opera do not have the required functionality to run the plug-ins properly. As of the 10.1.3 release of Reader, Firefox running in 32-bit mode is now supported on Mac OS.
What is the impact on LiveCycle Workspace?
Since LiveCycle Workspace operates in the browser, PDF Forms in Workspace don't function in Safari 5.1 using Adobe Reader or Acrobat versions earlier than 10.1.3.
What is the impact on Adobe Solutions Accelerators?
Interactive Statements
In the primary use case for Interactive Statements, PDFs are delivered via email and can be opened with the stand-alone Adobe Reader or Acrobat. The secondary use case, where the statement is generated and displayed on a website, requires Adobe Reader or Acrobat to operate in-browser and doesn't function using Adobe Reader or Acrobat versions before 10.1.3.
Correspondence Management
Internal employees (the Case worker/Claims adjustor and the business user personas) require Adobe Reader and Acrobat to function in-browser and don't function with Safari 5.1 using Adobe Reader or Acrobat versions before 10.1.3. External user use cases do not require that the Adobe Reader or Acrobat operate in-browser, so they aren't affected by the Safari 5.1 browser.
Managed Review & Approval (MRA) and Integrated Content Review (ICR)
Since the MRA and ICR solutions require Workspace, these customer use cases can't function in the Safari 5.1 browser using Adobe Reader or Acrobat versions before 10.1.3.
