SYMPTOMS
While you use the Netfx.msi Microsoft Windows Installer package to install the Microsoft .NET Framework 1.1, you may receive the following error message:

Error 1935. An error occured during the installation of assembly component {7D4B5591-4C80-42BB-B0E5-F2C0CEE02C1A}.

HRESULT: -2147319761.

When you click OK, the installation of the .NET Framework 1.1 stops, and you receive the following error message:

Microsoft .NET Framework 1.1 setup has ended prematurely. If this persists, please contact Product Support.

Note In the first error message, the word &quot;occured&quot; is misspelled. It should be spelled &quot;occurred.&quot;



CAUSE
After you install the Microsoft .NET Framework 1.0, the Windows Installer service uses the Fusion.dll file to manage assemblies. When you try to install the .NET Framework 1.1, the installation process upgrades the Fusion.dll file on your computer to a later version of the DLL. However, if you do not stop the Windows Installer service and if you do not restart your computer before you try to install the .NET Framework 1.1, the Windows Installer service still tries to use the original version of the Fusion.dll file during the installation process. Because the original version of the DLL is not available on your computer, you notice the behavior that is mentioned in the &quot;Symptoms&quot; section.



WORKAROUND
To work around this problem, use either of the following methods:  Use the Dotnetfx.exe file to install the .NET Framework 1.1. When you use this file to install the .NET Framework 1.1, the Windows Installer service on your computer is stopped before the installation process. To download the Dotnetfx.exe file, visit the following Microsoft Web site:
