Why I have a warning when I updated SUCCESFULY my site

[aspkiddy]

Hi,

I upgraded my joomla site from "Joomla! 3.2.0 Stable" to 'Joomla! 3.2.1 Stable' using "Joomla_3.2.x_to_3.2.1-Stable-Patch_Package.zip" on http://joomlacode.org/gf/download/frsre ... ackage.zip).

I received the following Warning message:

Message
Installing file was successful.


Joomla! 3.0 Content Management System.
Error on deleting file or folder /libraries/joomla/application/router.php
Error on deleting file or folder /libraries/legacy/menu/index.html
Error on deleting file or folder /libraries/legacy/menu/menu.php
Error on deleting file or folder /libraries/legacy/pathway/index.html
... etc

Why I have those error ? What must I do for this ? Is it serious ?

Thanks

------- my site on
Web Server : Microsoft-IIS/7.5
Database Version: 5.6.13-MySql
PHP Version : 5.5.3

It seems File permissions are wrong.
Joomla could not delete / move files.
If you can, you can change the file permissions or you can take the help of your web hosting service provider.

Thanks rameshelamathi,

I tried on other joomla Web site with your idea :

I changed the file permissions :
Permissions for IIS_IUSRS
I added "Full control"

And I haven't any warning...

Thanks
