If you are installing Magento directly on your server, then you may get some errors while opening the installation wizard on your browser, i.e, 500 INTERNAL SERVER ERROR. Its mainly because of the wrong FILE PERMISSIONS.
The best way to solve this issue is here,
1. Download Magento Cleanup Tool
2. Unzip magento-cleanup.php to the root directory where Magento is installed.
3. Browse to http://yourdomain.com/magento/magento-cleanup.php

Upgrading an existing Magento Version
It is now possible to upgrade your existing Magento installation to 1.1 through the Magento Connect Manager. To do so:
Do NOT use your live or production site. We suggest making a copy of your site and upgrading that copy first.
Log into your Magento Connect Manager.
Select the ‘Setting’ tab.
Change the Preferred State to ‘Stable’, and save settings.
For the Mage_All_Latest package select upgrade.
Click on the ‘Commit Changes’ button. The upgrade should start.
After upgrade is complete click on the ‘Refresh’ button.
You should now have Magento 1.1 installed.
But the result is this one after i refresh:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@cellassweetandsexytreasures.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
How can i fix this problem? I can’t even open the website. I hope you can help me. Thank You

There has been an error processing your request
Exception printing is disabled by default for security reasons.

I have enabled logging. How can i see what is the error.

What a great little tool. The first time I installed Magento, I spent about an hour figuring out the correct permissions. This time, less than a minute. AWESOME!
