Hello,
It can happen when timeout occurs. You can try to increase 'max_execution_limit' PHP option with help
PHP Settings plugin or install the component from directory, for this upload component archive to your server, unzip it and choose 'Install from Directory' method on Joomla! installation page. Usually hosting control panel provides ability to upload and extract file from archive, but it can also be done with help Joomla! extensions like
eXtplorer or
Ninja Explorer. If you have any difficulties with it, you can provide temporary access to your Joomla! backend by
email and we'll help to install the component.
Regards,
ARI Soft
