Measurement and Automation Explorer not installed correctly

I have a trial version of LabView 8.5.  Upon trying to change the Instrument I/O Assistant, I get "Measurement and Automation Explorer not installed correctly.  Please install from driver CD."  Well, I don't have the CD since this was a trial download.
 
Basically, what I am trying to do is this:  I want to pull 4 variables/tags from an Allen Bradley PLC and log them to an Excel spreadsheet.  I am using RSLinx to communicate with the PLC, and LabView to compile the info. 
 
Any help would be appreciated.

Any Ideas?  I have the program running right now, and I'm kinda in a bind.  I also tried RSView32 Works to log the info, but there isn't enough flexibility in logging.  I need to log flow rate test results from a large automated machine.  The mahcine does a number of operations, but we are most concerned with these four tags (since it conducts four tests at once).  The problem is, the cycle time varies with the lot of product.  Some products require more time as the process is more delicate.  So, I can't use a time-interval logging method.
 
As for variable change, I can't do that either because it records the 4 test results in series; not all at the same time.  That, and if the test is aborted (no tube), the previous test result value stays in the tag until there is a successful test.
 
I found a variable that changes once per cycle.  I'd like to log the four tags once per cycle.
 
BUT I can't do anything until I get the I/O Wizard working.

The device driver CD is available for download. See this post by Chris_R.

Thanks!  I installed the driver CD, but unfortunately, the I/O Assistant still does not work; it claims the drivers are installed wrong.  Aside from reinstalling, is there anything I can do?

There is a KnowledgeBase article on this error available here.  Make sure you uninstall the IO Assistant from add/remove programs and then reinstall the assistant from the drivers CD. 
 
Trying to install the drivers CD again without uninstalling first won't solve the problem since it would see that the latest version of IO Assistant was available and thus not reinstall support for it.

Ah, that makes sense.  I'll definitely give that a try, however, I found that my initial intentions with this program do not require MAX.  I will definitely need MAX later on.  Thanks for your help!
