Hi there,
I have noticed several posts about file uploads failing the MIME check in the downloaded component but the file passes MIME check in the sandbox environment
After having a similar issue I checked the php.ini file and found the following line was commented out (PHP Version 5.4.4)
extension=php_fileinfo.dll
For those having upload / MIME check issues in the downloaded component please make sure the above line in your php.ini file is not commented out - it can be found under dynamic extensions as shown below
AND don't forget to restart your web server for the configuration changes to take effect!

;extension=php_bz2.dll
;extension=php_curl.dll
;extension=php_fileinfo.dll <= uncomment this line and restart your web server
;extension=php_gd2.dll
;extension=php_gettext.dll
;extension=php_gmp.dll
Hope it helps someone save some time...
