I constantly get “The package could not be installed. PCLZIP\_ERR\_BAD\_FORMAT (-10) : Invalid archive structure” when I try to upload Bricks to a new website. This has happened on several builds so far. I have increased upload size, memory, etc. I have also tried re-zipping the files. I don’t know what else to try. Please advise. ---

Hi Michael, Thanks so much for your report! Unfortunately, I cannot reproduce the issue and we don’t have any other reports about it.

I’ve also been getting this error on both my Wordpress sites (one on [Hosting.com](http://Hosting.com), one on Cloudways). Every other theme and plugin works fine. Speaking with Claude I’m increasing memory limit to 256M, executing time to 300, and restarting PHP-FM, hopefully fixes… NOPE ☹ Given every other plugin works, other themes install OK, there must be something unique about Bricks triggering this. Downloading the update manually works but I can’t keep doing that. Extremely vanilla site. Just 5 plugins (Cloudways Site Manager, Regenerate Thumbnails, SEO Framework, Updraft Plus, Converter for Media). @timmse - I suspect many people are getting this, but ignoring it until it becomes a real problem. I’ve been doing that for a few months now. ---

Hi Simon, This thread is three years old, and unfortunately we haven’t received any feedback from the thread starter… It would be great if you could send us the login credentials for a staging/test environment where the issue occurs so we can test it safely ([help@bricksbuilder.io](mailto:help@bricksbuilder.io)). Please also include a link to this thread. Does the error message only appear for you during the automatic update? It seems the original poster was the other way around. > [@mrapino](#): > > …when I try to upload Bricks to a new website ---

Ah, figured it out. It was the licence! I’d copied/pasted an old cancelled licence code insstead of the latest one, so it must have been downloading a HTML error page instead of the zip. Leaving this here in case anyone else gets in the future.
