The software solution is based on Microsoft Visual Basic for Applications (VBA). The software solution creates an instance of the control directly through Microsoft Office. In this scenario, the control may not load in your solution.<br/><br/>To resolve this issue, delete the cached versions of the control type libraries (extender files) on the client computer. To do this, search your hard disk for files that have the ".exd" file name extension and delete all the .exd files that you find. These .exd files will be re-created automatically when you use the new controls the next time that you use VBA. These extender files will be under the user's profile and may also be in other locations, such as the following: <div class="indent">C:\documents and settings\username\Application Data\Microsoft\Forms<br/><br/>C:\documents and settings\username\AppData\Local\Temp\VBE</div></li></ul></div><h2></h2><div class="kb-moreinformation-section section"><h4 class="sbody-h4">Prerequisites to apply this security update</h4>To install this security update, you must have 2007 Microsoft Office Suite Service Pack 2 installed on the computer.<br/><br/>For more information about how to obtain the service pack, click the following article number to view the article in the Microsoft Knowledge Base: <div class="indent"><a href="" id="kb-link-9">949585 </a> How to obtain the latest service pack for the 2007 Office suite</div></div><h2></h2><div class="kb-moreinformation-section section"><h4 class="sbody-h4">Restart information</h4>You do not have to restart the computer after you install this security update.</div><h2></h2><div class="kb-moreinformation-section section"><h4 class="sbody-h4">Security update replacement information</h4>This security update does not replace a previously released security update.<br/></div><h2></h2><div class="kb-moreinformation-section section"><h4 class="sbody-h4">Removal information</h4>You cannot remove this security update.</div><h2></h2><div class="kb-summary-section section"><h4 class="sbody-h4">File information</h4>The English (United States) version of this security update has the file attributes (or later file attributes) that are listed in the following table.
