Windows – How to install .NET Framework without administrator privileges

-setupadministratorinstallationnon-adminwindows 7

I'm on my Windows 7 computer and want to set up .NET Framework. However it's asking for an administrator password but I have no idea what it can be. I really need the .NET Framework. I hope there's a portable version but I'm worried there isn't.

Does anyone know how to run the setup without knowing the administrator password?

Tried programs and trick:

Universal Extractor – it's only extracted not installed but they said it could install
cmd – tried all commands
Some password hack/viewer – none of them is working
Searched the whole computer for some passwords or things that can help

To install .NET you must have administrator privileges. Perhaps your administrator account is just disabled.

Try to boot into Safe Mode (F8 at startup) - the administrator account gets enabled there
Login as Administrator (maybe no password)
Go to users and give your account administrator privileges (add to Administrators group) or activate the Administrator user permanently

Windows – Allow given application to run as administrator, without prompting user for credentials

To accomplish what you want, the easiest thing I can think of is to create a scheduled task with the administrative credentials that will be run at a set time or interval.

You can manipulate scheduled tasks via the command line (schtasks.exe) or login script.

However, I have to warn you that whenever you intentionally make holes in your own security, you are asking for trouble later on down the line.

It will only take one smart ass in order to find the name of the .exe, and change it or put whatever he/she wants there instead - e.g. they can copy cmd.exe to the location and rename, then suddenly they have a command prompt with administrator privileges! (ok, you can use NTFS permissions and stuff, they could take the hard drive out - you can use Bitlocker/encryption...) the point I am trying to make is, it is a hole that you are intentionally introducing.

Another solution would be to re-architect the program. I would suggest as some sort of system service that does the work, and simply have a client that invokes the service as and when it is needed. This should work well.

Windows – .Net Framework issues on Windows 7 (probably after a gone-wrong SP1 update?) – Event Viewer won’t work, nor Zune

Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file. To do this, follow these steps:

Open an elevated command prompt.
- Start → All Programs → Accessories
- right-click on Command Prompt, and then click "Run as administrator"
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
Type the following command and press Enter
```
sfc/scannow
```
This command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

More info about the System File Checker in this Microsoft KB article.
