main script execution failed: poll

[derandrew09]

for all people who had the "main script execution failed" error.

i have seen this all over the place and cant even find a fix myself.

In the post below.. it talks about this.. its due to the installer.app not being compatible. You have to manually download and install 3.0b10. It is outlined in this post.

I have that version of installer and get the Main script execution error.

Does anyone know why this happens and how to fix it?

If you didn’t update Installer BEFORE updating to 1.1.3, or did but still get this error and need to fix permissions, try entering these commands via ssh:

cd /
cd Applications/
wget http://repository.apptapp.com/packages/System/Installer.zip
rm -rf Installer.app
unzip Installer.zip
chmod +s Installer.app/Installer
chown -R root:wheel Installer.app
rm Installer.zip

This replaces your copy of Installer with the latest version, and sets proper permissions.
