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.

    I myself think that I am annoying when it comes to this stuff, but when I get confused with something this important that I've spent so much time and money on, I MUST clear every little bit of fog.

    1. So you are saying to me that windows.old won't be available to me until I upgrade to Windows 8.1 and that, when I do upgrade, everything I had before, all 156GB of files and such that are currently in my PC, if everything goes correctly, can be taken out and put back so that, basically, my system is exactly the way it was before but, hopefully, without the .NET Framework issues?
    2. Does the way I am re-installing Windows 8 count as a "custom installation"? I do not believe it does, but if it does, does that mean that I will not be able to access the files?
    3. I am really unaware of what files I should've copied down, but I did these: "AMD APP", "GIGABYTE", "System", "System32", "SystemResources", "SysWow64", "Temp", and "WinSxS".

    I am looking for all the specifics and details here which is why I am hesitating so much to do this and it's also why I am asking so many question. I really wish that there was some way I could find a "step by step" process of this, even if it's 100 steps, because that is how much clarity I wish to have. But in my searches of the internet, I've not found such a guide.

    I apologize if I'm angering you or annoying you by appearing/being ignorant. :(

    Yeah. I ran the sweep and got the "No integrity violations found," text.

    So I am going to go ahead run the Windows 8 re-installation and hope that all goes well with getting all the files back properly.

    EDIT: I didn't run it yet because I was looking stuff up about a troubleshooter that can automatically re-install the files when I cam across a thought: All of my stuff may be saved in wondows.old when I re-install Windows 8, but if I upgrade to Windows 8.1 again, will windows.old disappear?

    Right now I am guessing that I just go ahead and run the troubleshooter to replace everything as soon as I get Windows 8.1 downloaded again, but it could be that i need to do it after Windows 8. I don't know, really.

    Don't think so. The Windows.old folder is created when you upgrade.

    You can check easily enough anyway by hitting Windows key + E to take you to your drives and then double click C:  to open it. You should then be able to see the Windows folder, but no Windows.old.

    If you do see it though, copy it to an external drive for safe measure.

    In any event, backup your most important files just in case. You should be able to find a 32GB flash pen drive somewhere locally I would think. Otherwise look for something like a 500GB external hard drive.

    So, because I must be COMPLETELY safe and certain, I simply want to know what are the exact steps I should take here.

    Here's how I am picturing this goes:

    1. I create the windows.old folder.
    2. I copy every file on my computer and place the copy in windows.old somehow.
    3. I re-install Windows 8.
    4. I open up the windows.old folder and take everything out.

    I am imagining, though, that that probably is not what happens.

    Anyway, when it says that all of my personal files will be saved, does it mean that EVERYTHING that I had before will be saved or will it throw out stuff like my downloaded drivers and games and other software that may not be considered "personal".

    I am really sorry if I am being a hassle. I've never been good with directions and likely never will be. Also, with a machine in which I've spent so much money, I don't want to put any of it to waste.

    Yeah. I am in CST, so the time I am posting this message is roughly ~3:10 p.m. for me.

    Apples,

    1. The Windows.old file is created automatically.

    2.  Also achieved automatically.

    1. Yes.
    2. Yes, but only what you think you want to keep.

    Before you go ahead though, try doing the following because I had a mammoth crash on my own machine yesterday and learned a few things along the way on how to fix something like this.

    • So first of all,  right click the Start button and go to Command Prompt (Admin).
    • Next, type: sfc /scannow and hit Enter.

    System File Checker takes about 30 mins to run and will attempt to fix any corrupted system files found. If it gives you a clean bill of health which will say something like "No integrity violations found", you can go ahead with reinstalling Windows 8.

    If on the other hand it tells you it found corrupted files which it can't fix, then we can run another tool to repair those. So hold off with the repair if this happens.

    I'll wait to hear from you again.
