Error code FFFF when trying to install Microsoft .NET Framework 3.5 Service Pack and .NET Framework 3.5 Family Update

Question

I've tried several times to install the Microsoft .NET Framework 3.5 Service Pack and .NET Framework 3.5 Family Update, always unsuccessfully.  The last time I was given an error code FFFF.  What does that mean and what do I need to do?

Hello Milleniars,

Thank you for visiting the Microsoft Windows Vista Community site.

I suggest you try to fix the issue with the steps in this link.

Error when you download updates using Windows Update or Microsoft Update: 8000FFFF

If the previous does not work, try to do a manual install of the two updates:

Unfortunately, the .NET Framework 3.5 SP1 redistributable does not include the latest fixes; hence, you need to run the other three afterwards. 

3.5 SP1 Redistributable:

Updates after the above installed:

Restart only after all four update are installed.

Let us know if these steps resolve your problem.  I hope the information is useful.
