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




I had the same problem & wanted to change the product key khổng lồ 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

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

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

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 lớn a trial, & 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 sầu CurrentSettings.vssettings first)Delete the license key from the registry by h& in regeditInstall Visual Studio using the publicly available website installer (which doesn"t have sầu 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

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


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