QUESTION:  
Why can't you have alarms and tag values displayed or exported on a Dat@View client (Dat@Monitor V6.0) with Windows NT 4.0?

ANSWER:  
In the case of a Dat@Monitor client with Windows NT 4.0 there might be errors in Dat@View with the Display and Export of alarms and tag values. The reason lies in the old versions of the Windows files msado15.dll and shell32.dll (4.00).

You should create an image of the hard disk before making the following changes.

Requirement for the display of data in Dat@View is the file msado15.dll with version V2.5 SP3 or higher. Furthermore, Microsoft Data Access Components (MDAC) 2.5 SP3 must be installed on the client. You can download this from the following address:

http://www.microsoft.com/downloads/details.aspx?displaylang=de&FamilyID=c57692e9-dde7-4a60-b586-5d4fd6794db6

Requirement for the export of data from Dat@View is the file shell32.dll (4.00). You can proceed as follows to install the latest version of shell32.dll:

• Option 1 (with Internet connection):
  To install the latest version of shell32.dll you must install Support for Active Desktop when setting up the Internet Explorer 6.0 SP1. However, since you cannot select this in the Setup mask, you should call the Setup for the Internet Explorer 6.0 SP1 with the following command from the command line:
  ie6setup.exe /C:"ie6wzd /e:IE4Shell_NTx86 /I:Y"
  
• Option 2 (without Internet connection):
  First deinstall the Internet Explorer 6.0 SP1 on the Dat@Monitor client, then install Internet Explorer 4.01 SP1 with Active Desktop and finally reinstall the Internet Explorer 6.0 SP1.
  
• Option 3 (without Internet connection):
  If you have a version of the Internet Explorer installed on your computer, which cannot be deinstalled and which is more recent than version 4.01 SP1, then you must reinstall Windows NT 4.0. Then you must again install SP6 (or SP6a), then Internet Explorer 4.01 SP1 with Active Desktop and finally Internet Explorer 6.0 SP1.
  
• Option 4 (without Internet connection):
  You also have the option of installing the new shell32.dll on a computer without there having to be an Internet connection and without having to deinstall the Internet Explorer 6.0 SP1:
  First unpack ie4slhnt.cab from the Internet Explorer 4.01 SP1 CD into a temporary folder (e.g. C:\Temp). Then install the files "ie4shell.inf" and ie4unit.inf by right-clicking the files and selecting the menu item "Install" from the pop-up menu. 
  Ignore the error message: "Copy error: an error has occurred while copying wallpaper.htm..." with the "Skip" button. Once you have installed both files you restart the computer. Then you install the Internet Explorer 6.0 SP1 again and restart the computer once again.
