Again : I/O Assistant not installed correctly.

Question

I Run LV 8.6 and MAX 4.5 ( XP, SP3 , AMD64x2-6 GHz , 4 GB RAM, 3 TB HDD ).
LV works perfectly.
However, I stumble upon the very same problem of the past when trying to run the I-O Assistant express.vi ( " MAX or Instrument I/O Assistant not installed correctly. Install from LV Driver CD "),
I installed the LV Driver CD ( the March 2008 1-2-3  version, this should work, it did in the past ).
But at present no I/O Assistant shows up.
Then I downloaded separately and installed the I/O-Assistant driver, but no success again.
I recall from the past I encountered this very same problem, which was resolved in one way or another but I failed to document how.
Help is appreciated.
Solved!

Martijn,
 Do you have the VISA functions in your functions palette?
Yes.
Or are there none instrument IO functions available?
They are
Next we can check if the InstrIOAsst folder available in the vi.lib folder (national instruments\labview xx\vi.lib)
Yes,  it says " InstrIOAsst " indeed, but this is not the " Instr Assist " express.vi from the Express>Input panel
or is the instr folder available?
Yes, i.e. " IO Assist " but when executing " I-O Assistant " it shows a peculiar " Instrument I/O Assistant Task " and not the wanted simple express " Instr Assist ".express vi
If they are we can try to fix the driver through the windows control panel. If they are not; please run the installer again and double check if the Labview 8.5 API has been selected; you may also consider to use a newer driver; NI VISA 4.6 .
I was puzzled and still am a bit, but WOW, as per your advice I deinstalled the NI-VISA 4.3 and downloaded and installed the 4.6 one and guess what ? It works.
I wonder why the 4.3 obviously failed since it did do the job in the past.
I wouldn't have raised myself the idea to reinstall the NI-VISA driver, so thanks.
Kudos !
Peter.
