When i try to install clientexec in softaculous appaers this error message at 10% install:
"Installation Failed : Please change the permissions of the config.php file so that it is writable by the webserver user (nobody). Please CHMOD all the subdirectories under the 'uploads/' directory to 755
(or better yet, just give them enough write permissions for your web server user).."
I just checked your ticket and you had provided access to your server, it seems you are using CGI and Softaculous settings were saved for suPHP :

We have made the required changes and you should now be able to install ClientExec. Can you please try installing it now and let us know if you still face the issue.
