IRuntime stuff like this should be stored in a subdirectory in the users home directory, a temporary directory, or be able to be configured with an environment variable.

To answer my own question it seems houdini does have an environement variable for this HOUDINI_ICON_CACHE_DIR. Instead of making the directory world writable try setting HOUDINI_ICON_CACHE_DIR.

I would consider this a bug with houdini. The program should never need write access to its installation directory. Runtime stuff like this should be stored in a subdirectory in the users home directory, a temporary directory, or be able to be configured with an environment variable. We work in a multi user environment and can not allow users to have write permissions to the vendor directories.
