This just and informational thread that OTN staff should look at.
The link to the Oracle Reports Conversion link does not work and download the tool when accessed directly using
the URL attched to this link.
Convert from Oracle Reports, Crystal and Actuate to Oracle BI Publisher
This path did work and I was able to download the tool successfully.
I chose the Overview tab
Scrolled down to Getting Started-> Converting To Oracle BI Publisher - New
That took me back to the same page but this time the download worked.
Thanks for reporting, will be resolved shortly.
