I am trying to install a trial of the Image Acquisition Toolbox, but keep getting an error on ~90%. Apparently it has something to do with org.apache.lucene.analysis.core.SimpleAnalyzer (see below for message from log file).
Even though it fails, it shows on 'ver', but 'imaqtool' freezes and gives an error (see below).
Any help would be much appreciated. Thanks

Yes, I had to tamper with Java to use WSDL (I installed OpenJDK). How can I reset it to "default" values? Thank you.

I have finally been able to run the toolbox installation without problems. This is what I did.
  1. Downloaded lucene version 4.6.1 from https://archive.apache.org/dist/lucene/java/4.6.1/
  2. In the Image Acquisition Toolbox folder (after downloading and decompressing it), one can find the folder /java/jarext
  3. In that folder there are 8 files called lucene-*****.jar, which I replaced with the files found in 4.6.1
I still haven't thoroughly tested everything, but at least the install was smooth. I'll post if there's any other problem. Thanks for your help, Walter.
