Hi,

I cannot install the MSDN library for VS2008 as the setup process resports the error: "Setup has detected that the HTML Help data files are corrupt and cannot continue"

The relevant part of the msi log is:

MSI (s) (9C:48) [10:00:21:628]: Note: 1: 2235 2: 3: ExtendedType 4: SELECT `Action`,`Type`,`Source`,`Target`, NULL, `ExtendedType` FROM `CustomAction` WHERE `Action` = 'CA_HHCheck_enu'

MSI (s) (9C:48) [10:03:06:081]: Product: MSDN Library for Visual Studio 2008 - ENU -- Setup has detected that the HTML Help data files are corrupt and cannot continue. Click Ok to close setup.

This seems to indicate that my nslist.hxl file is corrupt. A search of the Microsoft Help and Support pages suggests that there is a workaround for this problem, but do not have a description of what to do.

Best regards
John

Hi John,

I am moving this thread from Base "Visual StudioSetup and Installation" forum to the "Developer Documentation and Help System" forum, since the issue is related to Visual Studio documentation. There are moredocumentation experts in the "Developer Documentation and Help System" forum.

Thanks
