.Net 1.1 install failure & .Net 2.0/3.0 uninstall/repair/update failure

I have a program my company just purchased that requires the use of .Net 1.1. If it detects that it is not installed it tried to install it from the package. It does not give me the option not to, it just activates. I tried installing this program onto a specific Win XP SP3 machine and it hung on the .Net install portion. I realized this wasn't working so I canceled the install and ran windows update to install the Net1.1 manually. When i went to the update screen there was about 14 available critical upddates so I selected all of them and the downloaded the .NET 1.1 from the optional portion. After it finished downloading I got 3 failures.

.Net 1.1 install failure
.Net 2.0 SP1 install failure
.Net 3.0 SP1 install failure

I looked up the error codes in windows update history and I cross referenced them with MSDN, & support.microsoft.com, but I came up with "no results," I tried google but that didn't help either.

Anyhow, all the other updates installed fine so I thought I'd check to see if it was some odd anomaly. I reactivated the Windows Update after restarting and tried to update just one of the Service packs. (.Net 2.0 SP1) and it failed again. I wondered if it may have been a bad download so I stopped the Windows Update service and renamed the Software Distribution file which is where updates are downloaded. I restarted the Windows Update service and tried to rerun windows update for just .Net 2.0 update. It re-downloaded but the install failed again. I decided to download the .NET 1.1 redistributable from Microsoft in hopes to install it manually. I downloaded it but when I went to install it failed.

I decided to see if I can remove the existing .NET framework packages (2.0 & 3.0) and then try to install .Net 1.1. When I went to Control Panel>Add/Remove Programs and selected the uninstall it failed for both 2.0 and 3.0. i tried multiple times. I then tried to repair the packages which failed as well.

I don't use 2.0 or 3.0, I just want 1.1 to work. Can you guys think of anything that I may have missed? Thanks!

respawn--You usually need to have Windows Installer installed in order to install .NET Framework.

jcimarron, windows installer is mandatory before running windows updates. Thanks for the idea though.

OK so after some fiddling around with akahan idea I finally got it to work but not without some trouble. For reference I'll explain it all below but first and foremost thanks akahan for linking that software to me, it allowed me to get the ball rolling. I noticed that you and a version 2 of the .net cleanup installer (dotnetfx20_cleanup_tool) but you linked only version 1. Is there something wrong with version 2? Anyhow this is the story...

I ran dotnetfx_cleanup_tool that I downloaded off akahan and it asked what version I wanted to cleanup, I chose all because they were all FUBARed. It did it's thing and afterwords I decided to see if any of the .NET that were previously installed were still on the programs list. They were not so it appeared that they were removed. I then tried uninstalling a different program just because it shouldn't have been on there and I got an error where i don't think i should have. (PIC1)

So I'm like great there is no installer but I wanted to see if it was just something random so I tried installing .NET 1.1 and I got the same thing. I then tried running Windows Update because I know it checks for Windows Installer 3.1 to be installed before it let's you run updates. So I got into the custom update screen and when it downloaded and tried to install the service pack I got an error. (PIC2) This is the same error as I got before for a failed install.

At this point I accepted that my windows installer was FUBARed so I downloaded Windows Installer 3.1 Redistributable (v2) and ran the install in hopes to get a working installer running. Well I was met with another error (PIC3).

I figured if trying to install an equal version didn't work, maybe I should upgrade. So I downloaded Windows Installer 4.5 Redistributable which I was sure was never installed and it worked! The installer was loaded perfectly.

I then went to try to uninstall the old program that I tried uninstalling after I ran the cleanup and it removed the program without complications. So then I tried installing .NET 1.1 Redistributable and I was met with PIC4. (Sorry i was so happy that I figured I share in my happiness with a screen shot)

I then ran windows update to see if that was working and I managed to install .NET 1.1 SP1 and .NET 2.0 w/ SP1 for Windows Update. I was supper happy. I then tried loading the software that I originally tried installing and it installed and ran just fine! So now everything works!!!!

Thank you everyone for your help and suggestions and hats off to akahan one last time!
