Yes, Document Analyzer is stall available. The current version is 3.8. The download link works for me.
Try going directly to the "Tools" section of Qlik Cookbook and select it from the list.
I also have a complex app with thousands of objects.
After running test with Process Document mine stopped at this place
set openOutputFile with Permission denied at the top
I have the Analyzer 3.8 pointing at a complex large qlikview document
All the metadata in the qvwork directory seems to have been created but the process doesn't seem to complete. I have had it running over the last weekend and it still has not completed.
What can I do to see where its 'locked' or whats needed to be done.
