Dot Net Framework 3.5 SP1 Full Download

Just try and find this anywhere on Google!!!  What a mess.

Anyway, I’ve found the correct download.  btw, dotnet35.exe is NOT the correct download.  You can install it, but then when you do a Windows Update, yet another .Net 3.5 SP 1 update will be there, just as big.

The correct full install can be found in the “Microsoft Update Catalog“.   Do a search for 951847 and all the 3.5 SP1 downloads will show up.  It’s a bit confusing because there appear to be two identical XP x86 installs.  I think they’re the same.

When you download it, you get a folder with the following files:


The largest is the full install.  The others are merely updates if you already have 2.0 or 3.5 installed.  More confusion here with the filename including “IA64_AMD64” which makes it look like a 64-bit install.  But the file names begin with “X86” so they’re not for x64.

Here’s a direct link to the catalog page:

Update: This update doesn’t seem to work either. I still get the .net 3.5 SP1 220+MB patch required w/Windows Update after installing this one. I have no idea how to properly install this patch without going through WU. 😦
