Thanks for the help Crahak, I will extract the files from the .exe and use the .msi instead. I've had no problems with this app whatsoever, any version, since the start of the Unattended Disks! Problems with everything else mind - but this has been one of my 100% successes till now. I looked under the "Sticky: My Application Switches" at the top of the forum under AdobeReader and it said ok for V6 and V6.02, so I did look B4 posting - but methinks the author either aint tried V6.02 and is ASSUMING it will work or he has a different version to mine that suddenly rears-up with the time-honoured syntax.
