WOPR on NT4 ----------- After installing _any_ major component on NT4, you should re-install SP3. Thus: 1: NT4 2: SP3 3: Printers 4: Office 5: SP3 6: Office SR 7: WOPR. Also, please take note of the following: Now that RegClean 4.1a is available, you should use it rather than older versions. RegClean 3.0 and 4.0 inadvertently remove Registry keys needed by the Automation functions of Word 97, Excel 97, Access 97, PowerPoint 97, and Outlook 97. If this happens to you, and you get errors such as "Object required" or "OLE automation error," you can run a free Microsoft utility called Idisp.exe to restore the needed keys. Set your browser to http://support.microsoft.com/support/kb/articles/q165/8/61.asp. When RegClean 4.1 was released, it resolved these issues, but remained incompatible with NT.
