Acrobat 9.0 PDFConverter toolbar missing in Excel 2003

Question

For some reason the PDFConverter toolbar disappeared in my installation of Excel 2003. I remember an error message flashing up but apparently I didn't pay enough attention. That happens all to often unfortunately.
After an hour of searching several websites, including these adobe forums, I found a procedure that was written for Acrobat 7.0 but it also solved my problem with Acrobat 9.0. I added this thread in the forums with the intent of making it easier to find for the next person.
The answer I found is response #2 in this thread - http://forums.adobe.com/message/2152995
The question that began the thread is "Acrobat 7.0 Missing PDFMaker files and won't pdf files"

I have had this problem with nearly every version of Adobe Acrobat up to and including 9.0
Here are four things I do to resolve this issue in order of time/difficulty:
First, I made sure that the Adobe Acrobat plug-in wasn't disabled.
In any Microsoft Product such was Word, Excel, etc.  go to Help>About Microsoft (Word/project, etc) and then click on the 'disabled items' button.
If the plug-in is disabled, select it and enable it again.
Second,  I make sure the PDFMaker files are registered.
I open a command prompt and navigate to the PDFMaker plug-in dll files in Adobe.
In Adobe Acrobat 8.0  the file path is:
C:\Program Files\Adobe\Acrobat 8.0\PDFMaker\Office
I then type in:
regsvr32 PDFMOffceAddin.dll
That should enable the Office PDFMaker plug-ins.
Third, I make sure that the AcroDist.exe application path was configured properly in the registry.
If it isn't, I just create it.
Registry path:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
Look for the entry "AcroDist.exe"
If not there, create it - it is a 'Key". (right click on App Paths and choose New>Key)
In the AcroDist.exe  key the (Default) value should be:
C:\Program Files\Adobe\Acrobat 7.0\Acrobat\AcroDist.exe 
or
C:\Program Files\Adobe\Acrobat 8.0\Acrobat\AcroDist.exe
depending on which version of Adobe Acrobat you have.  Essentially you put the absolute path for the AcroDist.exe file in there.
The only other entry in the AcroDist.exe key should be the String Value Path.  If it isn't there, create it  (right click and choose New>String Value)
The name of the String Value should be Path and the value should be the path of the AcroDist executable.   e.g.:
C:\Program Files\Adobe\Acrobat 7.0\Acrobat\
or
C:\Program Files\Adobe\Acrobat 8.0\Acrobat\
Close out the registry and try to use the PDFMaker again
If that still doesn't work then I run a repair on Adobe.  If THAT doesn't work then I completely uninstall/reinstall.

In Adobe acrobat pro, go to the Edit/Preferences menu and select the internet menu and make sure the Display PDF in browser item is checked.
Click the Internet settings button and go to the advanced tab and make sure the Enable third-party browser extensions is checked.
THen open the 32 bit version of IE9.
