A few minutes before, I had 26.6 gigs of free space left. A few minutes later, my free space was 26.3 gigs. What happened? (Note: I cancelled an installation of .NET Framework 3.0 at that time because it froze.) I restarted my computer and it's still this way. What's the problem?

I dunno if Microsoft would automatically remove a failed download, but you can look in My Computer > C: > Windows > Microsoft.NET > Framework, and see if there's a folder for .NET Framework 3.0.

If there is, I'm not sure if you could just delete it, or have to somehow uninstall it.

Better minds than mine will surely step in on that one, but have a look and see what you have.

Edit: A failed install could be still on your PC. If it is, there is a way to get rid of it.

Thanks for the help Dennis! I tried out this tool and it removed all install failiures and leftover files I think because my HD space is back to 26.6 gigs!

Icedrake,
I am sure that Dennis just forgot that he probably has the Windows Installer CleanUp Utility.
The program that you used probably led to this utility.

I'm pleased you got it sorted Icedrake, and nice post davey.

I'm actually pleased you had no problems, as it's possible to corrupt the other .NET Framework Installations when you try to remove a failed one, because of the shared files and registry keys.

Thankfully we didn't have to go down the path of reinstalling all the other .NET Framework installations.

If you have any follow up problems with .NET Framework Icedrake, have a look here:

I'll have to add that one to my kit, because one never knows when those big bloated installs will go kaboom.

see my post [ Harddrive got full ] no one can tell way this happened to you.

Hi,
I just wanted to remind that this tool is just for .Net Framework clean up.
I used on May 05,2008 after using Add/Remove Programs to uninstall .Net Framework 3.5 Pre-release.
They both worked with no problems.
Also no problems installing release 3.5.
