10 | ## Installation instructions
11 |
12 | **Windows 7 users**: This extension requires PowerShell 3, please download and install PowerShell 3 for your OS architecture:
13 | * 32-bit: http://download.microsoft.com/download/E/7/6/E76850B8-DA6E-4FF5-8CCE-A24FC513FD16/Windows6.1-KB2506143-x86.msu
14 | * 64-bit: http://download.microsoft.com/download/E/7/6/E76850B8-DA6E-4FF5-8CCE-A24FC513FD16/Windows6.1-KB2506143-x64.msu
15 |
16 | After installing the extension, a page with instructions will open. You have to follow the instructions, otherwise this extension **won't work**!
17 |
18 | You will need to navigate to where the extension is installed (e.g. `%LOCALAPPDATA%\Google\Chrome\User Data\Default\Extensions\ihjgnaklogcickonfphakiihgjpkdheh\1.0.1_0\host\`) and run the file `register-host.bat`. This will enable the native host app that communicates with RegJump.
19 |
20 | In addition, you will have to download RegJump and place it in the `regjump` folder.
21 |
22 | ## How does it work?
23 |
24 | The main goal of this extension is to send the selected text on a page (which should be a registry path, e.g. `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT`) to a utility from Sysinternals called [RegJump](https://technet.microsoft.com/en-us/sysinternals/bb963880.aspx), which handles the actual opening regedit and jumping to the specified key.
25 |
26 | However, it is not possible to launch 3rd party executables from Chrome directly - that's not allowed for very good reasons.
27 |
28 | Previously, it was possible to use [NPAPI](http://en.wikipedia.org/wiki/NPAPI) to host a native plugin in Chrome (like Java or Silverlight), but that was deprecated, and as of recently, [removed from Chrome completely](http://blog.chromium.org/2014/11/the-final-countdown-for-npapi.html).
29 |
30 | This leaves only one option - using Chrome's [Native Messaging](https://developer.chrome.com/extensions/nativeMessaging). The idea is, the *user* registers a native host app (by adding a key to the registry) which communicates with Chrome by passing messages (json). The native host app can then do whatever it is programmed to do.
31 |
32 | In this extension, the native host app is a PowerShell script which takes in the selected text from Chrome, and launches `regjump.exe` (which the user also has to download himself and put in the specified folder), passing it the selected text.
33 |
34 | If RegJump can parse this text as a valid registry path, it will launch regedit with the specified path (like jumping to path in Procmon).
35 |
36 | Finally, since Regedit requires elevation to launch, you will always get a UAC popup asking you to confirm before launching the actual `regedit.exe`.
