In SharePoint 2010, sometime we try to browse the gantt
index pages, we can see the error as “Microsoft.SharePoint.SPException: This
view requires at least Microsoft Internet Explorer 7.0, Mozilla Firefox 3.0, or
Apple Safari 3.0.” as shown the image below.
We can get this error when user agents in SharePoint are not
permitted to crawl the content in SharePoint index server. We can fix this by
changing Gathering manager value in Registry. To do that Start -> Run -> Regedit
Navigate to following path,
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office
Server\14.0\Search\Global\Gathering Manager
In Gathering Manager, Search for “User Agent” and edit the
value. Update the value to
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1;
Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729;
Media Center PC 6.0; InfoPath.3; .NET4.0C; MS-RTC LM 8; Tablet PC 2.0)
Click on Ok Save the settings and restart the server.
