Hello

I just downloaded the Apprentice installer for OSX and have tried to run it for a few times. Quickly after entering my password the installer starts but gives this error:

“Install Failed

The following install step failed: run postupgrade
script for foldericon. Contact the software
manufacturer for assistance.”

The machine is a Macbook Pro 2.2 Core 2 Duo with 4GB of ram running OSX 10.5.6 and 1.74 GB of available diskspace.

Does anyone know what's causing this?

thanks

I'd love to see the log from Installer.app.

Try installing Houdini again following these steps:
1. double click on the Houdini installer to start the installer
2. from the Window menu select “Installer Log”
3. select “Show All Logs” from the pop-up at the top left of the log window
4. when the install fails, click in the log window and then select the File->Save menu item to save out the log
5. attach the log here

Sorry for the trouble. Hopefully we can sort this out.

I get this problem also, with Houdini 10.0.249.5

Do you have another version of Python installed? For example ActivePython? Or, via Darwin Ports or Fink?

Basically, a bit of Python that comes with OS X is failing to find another bit of Python that comes with OS X.

Installing a new version of Python can cause havoc with Houdini because Houdini is a 64-bit application, and very few other Python distributions are compiled 64-bit Universal.

I installed 10.0.280 today, with no problems, so as far as I know the installer is working correctly.

thanks for the answer, I'm gonna see if it's even possible to remove darwin ports and install a 64bit python. If not, I'll just boot into fedora and use Houdini there

OS X comes with 64-bit Python libraries, which Houdini uses, even though /usr/bin/python is 32-bit only. So, if you just want Python, use /usr/bin/python which is standard on all Macs, and you'll be fine.

Removing Darwin Ports is easy:

rm -rf /opt/local

It is possible to hack DarwinPorts to build 64-bit, but it's not worth the trouble unless you have a particular need for the DarwinPorts version of Python.

I hope that helps!

I think my problem is that I installed MacPython 2.5.4, and I can't find any info anywhere on how to restore it to be the “factory” python. I'm a bit of a OS X n00b It's funny… in the back of my head I hear this “…this is a unix system, I know this…” and still I'm quite lost in OSX.

up and running on Fedora Core 9 64bit, works fine

I should have known better than to try and use something else than Linux

anyhoooo back in familiar territory and going through the tutorials.
