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.

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.

Yeah, I know that feeling well.

Try running System File Checker just in case it's a protected Windows system file which has gone pear-shaped.

So right click the Start button and got to "Command Prompt (Admin)" and then type: sfc /scannow and hit Enter.

If you get a message that it found files which it couldn't repair, let me know and I'll show you what to do next.

I must admit that I am way too scared to try. :P

The Repair Tool did not work.

As for the link you sent me, it brought me to a tool that only verified which kind of .NET Framework I have and it verified that I do indeed have .NET Framework 4.5.1. However, I was unable to remove the .NET Framework via this tool, and because it is a site offering third-party software, I'm not sure if I should continue there. That aside, I'll do what I have to, but I would like to know where, if there is any on the site, I can find a removal tool for the .NET Framework or if I can find downloadable software anywhere on Microsoft's official site.

Thanks for the attempts, though.

I feel as frustrated as you do sometimes. It seems that the tools we need to fix issues with .NET simply haven't been released for the version which is installed when you upgrade to 8.1

You could possibly try overwriting the installation by downloading the same file manually from here, but I don't know if it will work: http://msdn.microsoft.com/en-us/library/5a4x27ek.aspx

Create a manual System Restore point as a precaution in any event.
