Hmm, it sounds like you're doing everything right. It also seems
like it's mostly working, but not actually installing the updates.
Here's what is supposed to happen (once the updater program is
1. try to download and read the 'latest version number' from
currently, this reads '001'. If you're not connected to
the internet, it should time-out.
2. read the local current 'update value' from the file
IFEFFIT_DIR/updates/update.dat, where IFEFFIT_DIR is the
directory Ifeffit got installed to.
3. if it could read both values and the web version is greater
than the local version, it pops up the display saying that
updates are available. If the local version and web version
are the same, the updater is done.
4. if updates are needed and you click the 'install' button, it
tries to downloads zip file(s) named
where XXX is the update level. The program shows its progress
in a text window, so you should see it trying to download and
then unpack these zip files. For ifup_001.zip, it should
unpack these files:
5. It then deletes the local copy of the zip file, and displays
the contents of updates/ifup_001.txt, which reads
Update #1 applies changes between 1.2.2 and 1.2.3:
- setting path_index now makes the selected path 'the current path',
and re-evaluates defined variables and path parameters to use
that path's values for reff, degen, etc.
- fixed error with spline() passing pre1,pre2 to pre_edge()
6. finally, it writes the current version to the local file
If more than 1 update is needed, it will download and upack them in
order. In the batch files that launch the ifeffit applications, the
updater is now run just before each ifeffit application.
Given all that, and your symptoms, I'm not sure where the trouble is
happening. It sounds like it is trying to download the zip file, so
it's getting pretty far. Some things to look for are:
1. does the IFEFFIT_DIR/updates directory exist? If so, is there
a file update.dat? What does it contain?
2. you could try downloading
and unpacking it (relative to the main Ifefffit dir) by hand.
Does that work? As this overwrites ifeffit_10.dll, athena
should report that it's using ifeffit 1.2.3.
What are the size and date for ifeffit_10.dll?
3.If that works, you could try writing '001' to
That should stop the updater from trying to install updates.
Of course, the problem might return at the next update, so
this isn't a very good long-term solution.
Hope that helps, and sorry for the trouble. Is anyone else having
this problem? If so, please let me know, either here or through
