Bugs fixed since 2009r1
Patches for bugs in this (2009R2) release
 6 November 2009: (12.1.0.7369) These are patches for various bugs found in Tecplot Focus 2009 release 2. The full buglist is here. With the exception of Windows, all patches are incremental, e.g., you should have Tecplot Focus 2009 R2 installed first and would need to follow the steps to update the releases.

Bug # Summary
6083, 6811 Various node-to-element map fixes that correct an imbalance of memory accounting and an under-indexing of an array causes crashes. (patch available here)
6962 Incorrect global face neighbor logic for ordered IJK data where the K dimension was larger than then I dimension. (patch available here)
7083 Internal change regarding which macro we use for max/min. This doesn.t affect the customer at all. (patch available here)
7143, 7265 Streamtrace bug where we had some faulty logic with quads collapsed to triangles. In addition we were examining an uninitialized array member that could cause some odd behavior with streams terminating early or late. (patch available here)
7197 A copy set function was incorrect and could cause a variety of weird behavior in Tecplot. Primarily it showed up when trying to select zones in the zone style dialog. (patch available here)
7198, 7217 The Zone Style dialog was using SmInteger_t for an index instead of EntIndex_t. This would have prevented the zone style dialog from working correctly with more than 32K zones or mappings. (patch available here)

Windows: Download the Windows setup program:

On other platforms:
Option 1: focuscd.tgz - A full installation tarball of all of the *nix platforms. This is about 663Mb. Extract using "tar zxf focuscd.tgz" then run "setuptec".
Option 2: Incremental patch just replacing binaries. (these are much smaller):
  1. Download the platform-specific file below. If you're not sure, type this:
    ls $TEC_FOCUS_2009/lib/ext
    and you should see something like "linuxg248x64.26"
  2. Mac OSX
  3. Extract its contents in your $TEC_FOCUS_2009 directory. For example:
    cd $TEC_FOCUS_2009
    tar zxvf linuxg248x64.26.tgz
    This replaces various files in the bin/ and lib/ directories.
  4. Start Tecplot.
