Net framework 3

Here is a post describing my struggle installing the .NET Framework 3.5 in Windows 8.1 PReview. The post also covers the alternate way to install the same from the Windows installation media. - Article by Kunal Chowdhury on Thursday, July 04, 2013


It was not as smooth as I thought while installing the Windows 8.1 as a fresh OS in my laptop. Though the OS & other major software installation was smooth, but I faced lots of issues while installing some software"s that need .NET Framework 3.5.

Did lots of analysis, tried various methods khổng lồ install the framework but all failed. At the over I got an perfect solution which resolved the problem. Thought to lớn mô tả in case you faced similar, will help you.


As I formatted my hard drive sầu and installed Windows 8.1 Previews as a fresh operating system, my system was completely blank và I had lớn install all the other softwares one by one. This is really a hectic job but it should not be that much problematic if the Windows installation provided me the .NET Framework 3.5 by default.


Yes, I faced hell lot of issues installing .NET Framework in Windows 8.1 as it was needed by some software like Live sầu Essential 2012. Though I was trying to lớn install it from various package, it was asking me all the time to lớn install .NET Framework 3.5. I was shocked when I saw the system asking me to Install .NET Framework 3.5 before installing .NET Framework 3.5. Did I mentioned anything wrong here? No, I wrote it correct. The system was asking me to install .NET Framework 3.5 before continuing the installation of .NET Framework 3.5.


The things that I tried

Let’s discuss what are the things that I tried. If you want to lớn know only the solution, just go to the next point else continue reading the struggle that I faced with this installation.


I had the .NET Framework 3.5 installer package available in my software collection already & first I tried lớn install from there when I saw the below screen when trying khổng lồ install the Windows Live Essential 2012. This is common because the Live sầu Essential need Framework 3.5 to lớn exeđáng yêu. I know it already from my past experience with the software.



My struggle starts at this point when I saw the same screen when trying the install the package i.e. install .NET Framework 3.5 to install the .NET Framework 3.5 itself. Isn’t it too annoying when it placed itself in a deadlock? That’s a perfect example.


I tried it twice from the same installation package and when failed, tried lớn tải về the installer from online by clicking the “Download và install this feature” button from the wizard. My bad, that threw me an Error Code: 0x800F081F with a message stating “Windows couldn’t find required files”, that means, the installer package link has been moved to a different location.


In the next step, I downloaded a new installer package from Microsoft Download Centre, same happened. WTH!!! Now I tried downloading it from the MSDoanh Nghiệp subscriber page. Had a bad luchồng for sure. Got the same screen with the same error message. Tried searching online and then tweeted about the error & the “Windows Support Team” replied. They asked me to lớn post a Forum thread stating the issue. OMG! They don’t have sầu the answer too! I spent a huge time (it’s more than 3 hours I assume) to lớn find out the issue and finally left the PC intact, posted a diễn đàn thread & went lớn sleep as it was late night in India already.


In the morning I woke up early (generally I don’t) và tried installing the same again but didn’t get any clue what’s going wrong here. Didn’t get any proper solution in the forum too. I don’t think some one already faced and/or solved this issue. In the next step of my struggle, I tried khổng lồ install it from the Control Panel –> Programs and Features –> Turn Windows features on or off –> .NET framework 3.5 (includes .NET 2.0 and 3.0), as shown here but that was also not a good try for me.


Tried searching in the Windows 8.1 installation truyền thông media but didn’t find any redistributable package of the framework inside the ISO image. If it is require by few applications, why don’t Microsoft provide it with the Windows OS itself. This way the over user will not suffer a lot downloading và installing it. That’s a good thought but when I posted it in my Facebook page, got different replies from different people. That’s a long story. Will not cover that here but yes, it comes with the Windows package but not available as part of the installation by default. Read my next point lớn know more about it.


Final Solution

Finally, I found a solution in an MSDN article (shared by Suprotyên ổn Agarwal sir) which helped me khổng lồ resolve sầu the issue. When this kind of issue happens with the .NET Framework installer package, we can install it directly from the Windows installation media using the “Deployment Image Servicing & Management” tool, in short DISM command line tool,  that helps you lớn extract the image from the Windows installer package & install it in the system.


The .NET Framework package is available under the “sourcessxs” thư mục of the Windows installation truyền thông and if you try lớn find the framework installer, you will not get it there. You have sầu khổng lồ use the DISM tool for that.

To install the .NET Framework from the Windows installation media, open the “Command Prompt” in administrator mode and provide the following command:


DISM  /Online  /Enable-Feature  /FeatureName:NetFx3  /All  /LimitAccess  /Source:x:sourcessxs


/Online targets the operating system you"re running (instead of an offline Windows image).

/Enable-Feature /FeatureName:NetFx3 specifies that you want to enable the .NET Framework 3.5.

/All enables all parent features of the .NET Framework 3.5.

/LimitAccess prevents DISM from contacting Windows Update.

/Source specifies the location of the files needed to restore the feature (in this example, the x:sourcessxs directory).

Once I provided the above sầu commvà in the console window, it started installing it from the Windows Installation Media. In my case, it was the ISO image of the Windows 8.1 Previews mounted lớn a virtual DVD ROM.


My Question to Microsoft

After struggling a lot, my simple question lớn the Microsoft Windows team who packed the installer: Why don’t you provide the said và required frameworks installed by default with the Windows installation? When I asked the same question to lớn my friends available in Facebook, I got many stated that it would be a huge install và hence will take a lot of time. Someone stated that, it would need a big installation truyền thông media and hence it would not be accommodated within a 3GB ISO image.


.NET Framework is not too huge. Max lớn max it will take 250-300 MB additional space if not already provided within the ISO image. If it comes with the mặc định installation, people will not face such kind of issues that I faced while installing .NET Framework 3.5. As it is used by many applications till date, it would be a good idea lớn paông xã it as the standard installation of the OS.


The good news is: it comes by mặc định with the Windows Installer package but the bad news is: it comes as an optional component. Hence, it will not make the installation media a bigger one as it is already there. Just the point is that, we don’t know (in general) that it comes by mặc định with the package which we can directly install using the DISM tool without downloading additional thiết lập from internet.


So, the question again comes: “Why .NET 2.0, .NET 3.0 & .NET 3.5 are not part of the standard Windows installation?” and I am still inside a dark big cloud until I get a suitable answer from Microsoft. I know, you will also lượt thích lớn get this answered from Microsoft and will be glad if they provide it by default with the Windows Installation.


It was a long post I know but I wanted to tóm tắt with you my experience struggling to lớn find the solution. It might take some amount of time reading the whole post without directly providing the solution but I know, it will be a good read for you lớn underst& the whole thing. If you already faced the same issue, you will not have to lớn bởi the same struggle và directly fix it by using the same steps with the DISM tool mentioned in the “Final Solution” section above.


If you had the same experience earlier before reading this post, nội dung the same with us. Thanks to Suprotyên Agarwal sir once again for helping me to lớn resolve the issue. Also my sincere thanks to lớn all those friends who helped me with various steps. I assume that this post will help you in future. Don’t forget khổng lồ share it to your friends or network and help them lớn gain the same knowledge that we learnt.
