sorry for my bad english.

I found the error and the solution, but I do not know if it's the right way.

The error is in the file: install.adsmanager.php
At the last code part:

// For Joomla 1.5
global $parentadsmanager;
$parentadsmanager = $this->parent;
// For Joomla 1.5
if(!function_exists('com_install'))
	{
	function com_install()
		{
 
		global $parentadsmanager;
		$class = new Com_AdsmanagerInstallerScript();
		$class->updateXmlJoomla15($parentadsmanager);
		$class->postflight("update",$parentadsmanager);
		return $class->install(null);
		}
	}

I deleted this part of code and the extension installeted success.
I think this does not cause any problems, because the comment reference to joomla version 1.5.

Is correct?

Sorry, I didn't know that you wanted to install it on a 1.5 version of Joomla.
Did you try to reinstall it once the first install worked ? Sometime a reinstallation solve the component not found issue.

Best regards.
