CAUSE
This problem occurs if you try to install or remove RealPlayer 8, but the process fails. If the %systemroot%\System32\Drivers\Asctrm.sys driver file is removed, but the corresponding registry keys are not removed, the system tries to start the driver and does not find it. You then experience the problem that is described in the &quot;Symptoms&quot; section of this article.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To resolve the problem, do one of the following:  Reinstall RealPlayer 8 (and then remove it if you want to). Manually remove the registry key that associated with Asctrm.sys. To do so:  Click Start, and then click Run. In the Run dialog box, type regedit, and then click OK. Locate, and then click the following key:



 On the File menu, click Export.</li> In the File name box, type ASCTRM Backup, and then click Save.</li> On the Edit menu, click Delete, and then click Yes to confirm the deletion.</li> On the File menu, click Exit, and then restart the computer.</li></ol> </li></ul>
