Installing Discoverer 10.1.2.3 Client Software on Vista (32 & 64-bit)
Although not Federal specific, I thought I’d post the steps I came up with a ways back to install the latest Discoverer client tools (Desktop and Administrator) on Vista as there’s a bit more to the approach than a couple clicks. I know of a number of users who fought with the process for a few days, so just follow this if you need to install and you should be good to go. A co-worker recently confirmed this approach also works for Vista 64-bit. Here is the doc I put together.
-Update 1June09: I did successfully install on Vista 64-bit using the doc. I added two items to the doc: 1) Be sure to always execute the install processes as Adminstrator (right click on the setup.exe and select ‘Run as Adminstrator), and 2) I suggest using a short path name for where you unzip the files (e.g. c:\oraclesoftware\BI Tools 10g), as the installer seems to fail when executing from a directory with a long path name.
