Resolved Product Builder 6.6.4 Update not working

Good day,

I'm updating Joomla and my plugins and extensions.
All the other extensions (Custom Filters, Virtuemart and Stockable Custom Fields) are updating from 6.6.3 to 6.6.4 apart from Productbuilder.
I've tried it via the update option in the Joomla Extension manager and by downloading the extension (plg_csviaddon_productbuilder_csvi_6.6.4.zip) and installing it (how I would normally install extensions).

In update manager it comes up with the errors:
- Error Unable to open archive
- Warning Update path does not exist.
- Message Error updating COM_INSTALLER_TYPE_TYPE_.

In the install manager it comes up with the following errors:
- Warning JInstaller: :Install: File does not exist /var/www/http://btechsolutions.com.au/tmp/install_57d0a326315c5 com_productbuilder
- Plugin Update: Could not copy files from the source.

I've even chmod -R 777 my complete Joomla directory (what I sometimes quickly temporarily do when and update or extension won't install) but this also didn't work.

Also cleared my cache.

It seems like something in the update?
I was actually able to install version 6.6.3 (plg_csviaddon_productbuilder_csvi_6.6.3.zip) no worries. That why I'm suspecting version 6.6.4 to be something wrong with but of course it could also be something on my end maybe?

Thanks, Ray
