Unable to install .NET Framework 3.5 through SCCM on Windows 10

I recently had to uninstall/re-install .NET Framework 3.5 on my new Windows 10 work machine to troubleshoot another issue. I have to install it via SCCM due to Group Policy blocking Windows Updates (so I can't just install via Control Panel > Turn Features On/Off).
When attempting to re-install through SCCM the install just spins in the Installing state indefinitely until it times out.
Steps taken:
Uninstalled the .NET 3.5 Framework via Turn Windows Features On and Off in Control Panel and restarted machine.
Went to SCCM and attempted to install software, and it hung indefinitely.
After 2 hours I restarted machine to check if I just wasn't alerted it was finished for some reason
Install did not finish, Failed status shows with the error code for timeout in SCCM.
Other Info:
I verified no errors were generated in the SCCM log files or Event Viewer.
I can't install via Control Panel MS Update download as mentioned above due to Group Policy, I can't do an Offline install b/c these laptops don't have a disk drive (for whatever reason that was decided to be ok), and I can't do a system restore to before I removed it due to drive encryption software.
No admin accounts or similar can get different results, and I've verified it is not the SCCM install itself after getting it to install on another machine just fine.
I've ran both the .NET Framework Repair tools and Clean-up tools and I still get the issue.
Any ideas on what I can try?

If anyone encounters a situation similar, I was able to fix it by extracting the microsoft-windows-netfx3-ondemand-package.cab file from the .iso of Windows 10.
Using that file you can run the following script in an elevated (administrator) powershell and it will install the files offline for you.
Dism /online /enable-feature /featurename:NetFX3 /All /Source:<path to file>

LTSB Windows 10 Store App

we need to install a windows store app on a windows 10 LTSB.
Is it somehow possible to legally get an appx package of a store app so we can install it or are there some other ways to do it?

If you go to Settings > Updates and Security > For Developers Go to Use Developer features and select Sideload apps.
Then you will need to install the certificate for the application, This will be bundled with you appx package. Import the certificate to the local machine under the Trusted Root Certification Authorities folder.
Finally, sideload your app onto the machine using Powershell and the Add-AppxPackage cmdlet.
You will now have the application installed on that Windows 10 Machine.
EDIT:
I notice you are wanting to install an app you havent created, already on the app store, following these steps had some success to get apps running on LTSB version of Wiindows 10.
As from http://answers.microsoft.com/en-us/windows/forum/windows_10-start/windows-10-enterprise-ltsb-no-more-built-in-metro/ab8dbbe5-ef56-47c0-98a0-4a9a7d9763b8?auth=1
Grab C:\Program Files\WindowsApps from Install.WIM on a Windows 10
Enterprise CB ISO
Place them as you see them in the WIM on your real system
Add-AppXPackage -Register 'C:\Program
Files\WindowsApps*\AppManifest.xml' -DisableDevelopmentMode
(Repeat the last step 2 more times to work around dependency hell)
Do as this article tells you to do:

Uninstalling Windows Hotfix via C# or PowerShell

In our Company we need to uninstall a Windows Hotfix thats installed on the System. I've done a PowerShell Script that checks if the specified Update (Lookup via KBArticleID) is installed or not and then reports this via Textfile to the Server.
There is a Windows built-in Tool called WUSA (Windows-Update-Standalone-Installer) that allows to uninstall Updates with a specified KB-Article-ID. The Problem is that under Windows 7, 8.1 and 10 the WUSA-Tools only works in normal interactive Mode and not in the quiet Mode that we need. I'm running like this:
wusa.exe /uninstall /kb:3114409 /norestart /quiet
As described the Problem is that this command will only run in Interactive Mode and not Quiet.
Do you have any solutions or hints? I would prefer to implement this via PowerSehll or C# but other Solutions are welcome too :)
Thanks for your help!

Old post, but the heck..
I tried this on a windows 2012 R2 server and it worked:
Start-Process wusa.exe -ArgumentList '/KB:3170455 /uninstall /quiet /norestart' -Wait

How can I repair .NET Framework 4.0 on Windows 8?

While trying debug my real problem, I'm trying to repair the .NET framework, because it looks like something in System.Data.SqlClient is hosed. But you can't uninstall this because it's part of the OS in Windows8, and you can't install it because it's already installed, and so I can't find any way to fix my problem. I suppose I could reinstall the whole OS, but that's way too painful.

To Repair corrupted Windows files in Windows 8, open a command prompt with admin rights and run this DISM command:
DISM /Online /Cleanup-Image /RestoreHealth
This downloads the clean files and installs them correctly.

Where can i find msi install of postgresql-9.1.3.1
Thank you
Zak

postgresql-9.1.3-1-windows-x64.exe can be downloaded from sourceforge. This link might help you for silent installation.

I've the same problem with PostgreSQL on Windows7 x64, well the solutions that success for me is:
Create user postgres and set up password. (User Administrative Tools).
Create C:\postgres and set up security full control to user postgres.
Execute installer and set C:\postgres as root directory
Enjoy it xD
that is all.

Run this command:
postgresql.exe --mode unattended
--superpassword youpassword
--serverport 5432
--unattendedmodeui none
--prefix "c:\postgrespath"
--datadir "c:\postgrespath\datapath"
