The problem is most likely the configuration of your PHP server. Many PHP servers are installed by default to allow a single file upload to not exceed 2MB, and some plug-ins are larger than this.
You may be able to control this by adding the following lines to your .htaccess file in the root directory of your domain. Note that the values you enter here may be restricted by the PHP server limits. If you still have problems, contact your host's tech support.
I have exactly same prob joomla 1.0.13 and cb 1.1 i tried php memory increase solution in htaccess and in php.ini but its not working i can install the plugins using "Install package from web (http/https)" option but
not by browse upload and install option i am using this on local server wamp

I have the same problem on joomla 1.0.15 with cb1.1. all my local directory are on 777, my php values for upload are on 20M
So i don't understand why this error.
But, you can pass it by uploading you plugin in \components\com_comprofiler\plugin\ directory (unzip files first) and do an install from directory.
I passed the installation of the french language plugin.
I have this problem as well. I did some research and it seems some hosts fails to create a directory when the trailing slash is given. I was not able to install anything in the admin, but found a hack for the joomla core installer component. That sovled my issue with all other installs, not CB though. It seems like CB is using it's own installer and maybe it'll need a fix too? The fix I found is here: forum.joomla.org/index.php/topic,130060.msg638844.html
Well, it seems I solved it myself when I finally found the plugin-installer functions
Just apply the fix from the link in my previous post to [code:1]administrator/components/com_comprofiler/library/cb/cb.installer.php (row 667)[/code:1]
That did the trick for me
