<p><span style="font-size: 12pt;"><strong>Problem</strong>:<br /></span>Opening an MS Office file directly from HyperDrive in windows Vista causes the file to be "Read-Only".<br /><br />The HyperDrive mounter uses a WebDAV connection created by the Microsoft Windows "Net Use" command. This issue arises when a user directly opens an Office 2007 file from a WebDAV mount. It is is due to Office 2007 incorrectly trying to open a connection to the remote server using port 445, a port that is blocked by some Anti-Virus software and some ISP's. Microsoft has not yet released any formal statements relating to this issue but it has been widely reported within their development community.<br /><br /><em>Note: the problem only affects files opened by Microsoft Office 2007 and will not affect the use of other files.</em> <br /><br /><span style="font-size: 12pt;"><strong><span style="font-size: 10pt;">Affected Clients</span></strong><br /></span>The problem affects Windows Vista users that are using Microsoft Office 2007 and that have one of the following Anti-Virus programs installed:<br /><br />- AVG<br />- McAfee<br />- Kaspersky<br />- Bit Defender<br /><br /><span style="font-size: 12pt;"><strong>Solutions</strong>:</span><br />-- Drag the file out of HyperDrive to the desktop, open and work on it from there, save the file, drag it back to the HyperDrive folder.<br /><br />-- uninstall the AV client and use a different one (like Norton).</p>
