I have a copy of MS Visual Studio from Microsoft's MSDN Academic Alliance.My university provided me with all needed info to get it.Now I need something like license information about my copy - type and number.Where do I find it? Here is the pic from Help->Register Product Menu

  1. Where can I find what license key was used in my installed copy of Visual Studio 2008? Find serial keys of Microsoft Office 2000, 2003 and Microsoft 2007. How do I change the license key for an installed copy of Visual Studio 2010?
  2. Where to find your product key depends on how you got your copy of Windows: From an authorized retailer. The product key is on a label or card inside the box that Windows came in. For more info, contact your hardware manufacturer. A new PC running Windows. The product key is preinstalled on your PC, included with the packaging the PC came in.

After all, product key and license key for current installation of Microsoft Visual Studio 2010 can be found at

.Program FilesMicrosoft Visual Studio 10.0Microsoft Visual Studio 2010 editionsetup.sdb, in the Product Key section.

Here is the page on MSDN forums about it.

If this file is missing (some installations do not have it), you can find it in the registry:

I have a Copy of Visual Studio 2012 Pro on my machine with a Serial key that i'm no longer suppose to use because i have to use another one. My problem is i keep Uninstalling Visual studio but the Registration information is still there after re-install and i cannot figure out which registry path i have to delete (i deleted a few) with no luck.

Is there a easy way to remove tha reg info or swap my keys?

I had the same problem and wanted to change the product key to another. Unfortunate it's not as easy as it was on VS2010.

The following steps work:

  • Remove the registry key containing the license information:HKEY_CLASSES_ROOTLicenses77550D6B-6352-4E77-9DA3-537419DF564B

  • If you can't find the key, use sysinternals ProcessMonitor to check the registry access of VS2012 to locate the correct key which is always in HKEY_CLASSES_ROOTLicenses

  • After you remove this key, VS2012 will tell you that it's license information is incorrect. Go to 'Programs and features' and repair VS2012.

  • After the repair, VS2012 is reverted to a 30 day trial and you can enter a new product key. This could also be used to stay in a trial version loop and never enter a producy key.


For those who will need to remove product key from Visual Studio 2015:

  1. remove registry key HKCRLicenses4D8CFBCB-2F6A-4AD2-BABF-10E28F6F2C8F
  2. repair Visual Studio installation

That's it, now you can change the product key if necessary.

For me, with Visual Studio 2013, it wasn't enough to remove the license key and perform a repair (the repair restored the license key instead of reverting to a trial, and running it without the repair (after deleting the key) claimed the license had expired but wouldn't let me enter a new key).

I had to:

  • Discover what license key Visual Studio was looking for in the registry with Process Monitor (it was HKCRLicensesE79B3F9C-6543-4897-BBA5-5BFB0A02BB5C)
  • Completely uninstall Visual Studio 2013 (save CurrentSettings.vssettings first)
  • Delete the license key from the registry by hand in regedit
  • Install Visual Studio using the publicly available web installer (which doesn't have any baked-in license key -- it installs a 30-day trial)
  • Enter my new license key
  • (Re-)install updates (Update 1 at this time)
  • Restore settings by importing the backup I made of CurrentSettings.vssettings

To see what's inside these HKCRLicenses useAPI Monitor v2

sample data that'll come out from CryptUnprotectData:

Useful here is maybe the Installation timestamp (11.10.2015 here )Change this would required to call 'CryptProtectData'. Doing so needs some efforts like written a small program OR stop with ollydebug at this place and manually 'crafting' a CryptProtectData call ..

Note: In this example I'm using Microsoft® Visual Studio 2015

-> For a quick'n'dirty sneak into an expired VS I recommend to read this post. However that's just good for occasional use, till you get all the sign up and login crap properly done again ;)

Okay the real meat is here:
%LOCALAPPDATA%MicrosoftVisualStudio14.0Licenses ^- This path comes from HKCUSoftwareMicrosoftVisualStudio14.0Licenses715f10eb-9e99-11d2-bfc2-00c04f9902351


-after some Base64 decoding:

Seems M$ is using JSON Web Token (JWT) to wrap in license data.I guess inside CertificateBytes will be somehow the payload - you're email and other details.

So far for the rough overview what's the data inside.

For more wishes get ILSpy + Reflexil (<- to changes/correct little things!) and then 'browser&correct' files likec:Program Files (x86)Microsoft Visual Studio 14.0Common7IDE**Microsoft.VisualStudio.Licensing.dll**or check out 'Microsoft.VisualStudio.Services.WebApi.dll'


For those of you using Visual Studio 2017 Professional, the registry key is:


I also recommend you first export the registry key, before you delete it, so you'll have a backup if you accidentally delete the wrong key.

See my UPDATE at the end, before reading the following answer.

I have windows 8 and another pc with windows 8.1

I had License error saying 'Prerelease software. License expired'.

The only solution that I found which is inspired by the above solutions (Thanks!) was to run process monitor and see the exact registry keys that are accessed when I start the VS2013 which were:


Separation studio serial number

like what are mentioned in the previous posts. However the process monitor said that this registry is access denied.

So I opened regedit and found that registry key and I could not open it. It says I have no permission to see it.

SO I had to change its permission:

  1. Right click on the 'HKCRLicensesE79B3F9C-6543-4897-BBA5-5BFB0A02BB5C' key
  2. Permissions
  3. Add
  4. In 'Enter object names to select' I have added my windows user name. Ok.
  5. check on Full control
  6. Advanced
  7. Owner click on 'Change'
  8. In 'Enter object names to select' I have added my windows user name. Ok.
  9. Ok. Ok. Ok.

I found that this registry key has several sub keys, however you have to restart regedit to see them.

By seeing which other registry keys are access denied in process monitor , I knew that VS2013 will specifically deal with these subkeys which are ACCESS DENIED also:061810bcad

and these subkeys should be changed their permissions as well like above.

After making these permission changes everything worked well.

The same thing has been done to Microsoft visual studio 2010 because an error in the license as well and the solution worked well.

UPDATE :It turned out that starting visual studio as administrator solved this issue without this registry massage. Seems that this happened to my pc after changing the 'required password to login' removed in the user settings. (I wanted to let the pc start running without any password after restart from a crash or anything else). This made a lot of programs not able to write into some folders like temp folders unless I start the application as admin. Even printing from excel would not work, if excel is not started as admin.

The ISO is probably pre-pidded. You'll need to delete the key from the setup files. It should then ask you for a key during installation.

The solution with removing the license information from the registry also works with Visual Studio 2013, but as described in the answer above, it is important to execute a 'repair' on Visual Studio.
