Inability to Uninstall Windows.NET Framework 4.5 and Other Versions

Anonymous

My current OS is Windows 8.1 64-bit.

Recently I have been coming across a Windows error that states this: "The application was unable to start correctly (0cx0000135). Click OK to close the application." This error occurs for a variety of applications, such as GeForce Experience.

Another error that has occured is the inability for any application to start up at all. While 0cx0000135 error wasn't happening too often, this error of a program telling me that it is about to start then not doing anything is popping up fairly often, like for XSplit. I have XSplit on my taskbar and I click it and it begins to start up, but then it suddenly just stops. And this has been going on for MANY applications.

I'm not getting any errors with my system aside from those two, and everything that I have looked up about the application error leads me to believe that my Windows.NET is not functioning properly. Many sites recommend un-installing it and then re-installing it, which I have found myself incapable of doing because it doesn't appear in the "Programs and Features" part of my "Control Panel". I've tried deleting the files of c:/Windows/Microsoft.NET and that didn't work because many of those files could only be modified by the "TrustedInstaller", even after attempts to change the capabilities of the users.

Also, I believe that I have version 4.0 or version 4.5 at the latest (even though I honestly can't tell), but when I attempt to download 4.5.1, it tells me that I can't, even though I believe that I do not have version 4.5.1.

So I would like to know what I can do to uninstall the program safely and then re-install it.

After all this I am still running into issues even though I thought everything was fixed and I've tried most everything I have found, though not everything. All I can say is that I've pretty much come up with the fact that it is the .NET Framework that comes with my OS that is malfunctional. I ran the methods listed here as well: http://support.microsoft.com/kb/976982 on top of doing everything that was listed in this thread.

So I am still left with the question if there is any definite way I can un-install my current Framework from my OS even though it came with Windows 8. Or perhaps there are some Windows 8.1 clean-up tools that are available or something like that.

I have managed to get a few things working, though, and I made sure that I fixed that CNBJ2530.DPB" of prncacla.inf issue because the sfc/ scannow command tells me that there are no issues, but I did not make another text document to see the results. One thing I got working was GeForce Experience all though it doesn't run as fast as it should. I start it up and it takes 20+ seconds to start, followed by a " unable to connect to nvidia try again later" message, followed by the program starting up. But I should be able to download drivers in the program and I can't because it keeps telling me to check internet connections, but I can download drivers from NVIDIA's site perfectly fine.

Apples....

Is it a PC or a laptop?

If it's a laptop, you cannot uninstall 8.1 which would be the only way to remove .NET 4.5.1 since the latter is only installed when you upgrade to Microsoft's latest incarnation of Windows.

And I've just read that the8.1 upgrade destroys the manufacturer's Recovery partition so that you can no longer use it to revert to Windows 8.0

If it's a PC and you have an installation disc, then you can reinstall Windows 8.0 again , sort out your .NET problem and then upgrade to 8.1 again. The latter will include .NET 4.5.1 of course and might place you back in the same boat you find yourself in now.

So all this and I may be finally beaten by the fact that I do not have the product key with me.

The disc is currently in my PC and I ran the set-up, but it requires the product key. I had my PC built for me and I discarded most if not all boxes for the original parts. So will I have to manage to get support somehow or do any files on the disc or anywhere on my computer, for that matter, contain the product key?

EDIT: I have the small package that contained the disc, but I see no 25-character key, I think. I see a 14-character text under a small bar code and an eight-character text above said bar code and to the right of another. I'm not sure if these are significant at all though.

If you reformat, everything will be wiped including .NET Framework.

When you reinstall Windows 8.0, you'll get .NET 3.5 (which includes earlier versions), 4.0 and 4.5 automatically.

What you should do after installing all the drivers for your system is to download all the patches from the Windows update site.

If you get any problems updating Windows 8.0, run this Fixit: https://support.microsoft.com/kb/949104/en-gb

Then it'll be time to upgrade to 8.1

After you install that, be sure to install these two Rollups. They're offered as Optional updates, so won't install automatically, but they each contain many fixes which might prevent issues in the future even if you don't have them now.
- January 2014 Rollup: http://support.microsoft.com/kb/2911106/en-us
- February 2014 Rollup: http://support.microsoft.com/kb/2919394/en-us
Thanks for the compliment by the way. Always nice to know :)

It is a desktop and I do have the disc so that means that I can make it Windows 8.0 again, hopefully. As for fixing the .NET problems, if I go ahead and re-install Windows 8.0, can I then delete the .NET Framework some way or should I just, as soon as I revert back, download 8.1 again and hope it works out?

I'm sorry if I'm making this out to be way harder than it actually is, but I want to make sure that I don't make any rash decisions and you, Xircal, really seem like you know your stuff.
