I got this error after update to Joomla! 3.3. I'm finding extensions do not install from the Web. I get the following error:

Warning

Error
Archive does not exist
COM_FINDER_INDEXER_INVALID_DRIVER

Message Popup Error:

SOLUTION

- Login to the Joomla dashboard
- In the left menu, click the Global Configuration link
- At the top of the page, you will see several tabs such as Site, System, Server, etc. Click the Server tab.
- Next to Path to Temp Folder, enter the full path to your tmp folder and then click the Save button in the top left of the page.
- By default it will be set to (path/to/joomla)/tmp
- If the new temp folder does not exist, Joomla 3.0 will attempt to create it the next time it needs it.
