.net Framework 4 issues

[Criss]

Okay so I accidently installed two copies of .net 4 framework which caused a error. I followed the instructions to remove it and when I tried to reinstall It wouldn't let me reinstall. This is the error I got

Can someone help me please?

What versions of Microsoft .NET Framework are listed in add/remove programs?
You should see, at most, any combination of:
1.1
4 Client Profile
4 Extended
4.5
and possibly (but not likely) some with Multi-Targeting Pack.

It's also possible the error you mentioned at the start isn't actually because of installing 2 copies (which shouldn't happen anyway) but because of some other factor instead. Posting the actual error may help diagnose the issue further.

I actually know its because it was because I installed two copies (Errors didn't start happening till then)
Here is the errors (Well a form of it,sometimes it changes 1 or 2 things but its always .net 4 framework stuff)

Im assuming this is what you meant,unless you mean the error I get trying to install .net 4,cause all it says is "Fatal Error" and gives me those logs

I found this information and troubleshooting steps from the knowledge base. I'm not sure if you've tried it, I got some hits to other posts that may have been you, so I apologize if I'm leading you in circles

Error codes “0x80070643” or “0x643” occur when you install the .NET Framework updates.

Some 'generic' stuff you could give a go, though- you could try running sfc /scannow in the run dialog (Windows Key+R). This could fix any issues with the Windows Installer Database which could be causing these sorts of issues.

Another thing to try is uninstalling every .NET Framework version, then install the version you need for the software you are trying to run. One utility you can use for cleanup is the dotnet Cleanup Tool, and remove all versions. Then you can install using the standalone .NET 4.0 installer (to avoid possible issues from the standard web installer).

Unfortunately the error code the CLR gives (800040005) translates to a less than helpful "unspecified error", so there isn't a lot to go on. The error lists some log files that might have extra information on the problem if you can find and attach them to a post.
