How do I fix an “Invalid license data. Reinstall is required.” error in Visual C# 2010 Express?

Question

I\'ve tried to install Visual C# 2010 Express edition onto my PC, but whenever I try to run it, I get a error message.

Invalid license data. Reinstall

Answer 1

I just right-clicked, and opened with Visual Studio XXXX (in my case 2015). Then save it. Done.

Answer 2

I have had this EXACT problem with VS2010 Professional Trial / Evaluation download. I can provide clear and concise steps to reproduce:

1. Set your system clock ahead by 1 day (oops!)
2. Install the trial software.
3. Set your system clock back to the correct date.
4. Start VS2010, you will receive the vague message indicating "Invalid license data. Reinstall is required."

In my case, the resolution was quite simple - set the clock back ahead to the wrong date. The next day, I was able to set the clock back to the correct date and continue using the product.

Based on other answers to this question, it would appear there are numerous reasons that you could receive this message. This specific issue is most likely to be encountered by someone with a "virgin" install of Windows since it is not so difficult to set the clock incorrectly when setting up a new computer and then fix it later (and if you fix the clock hours after installing the product, it might be hard to put it all together and realize what happened).

Hope this helps someone else.

I met the same problem yesterday.And I fixed already. Please follow the steps:

• Run setup.exe again; Change or Remove Microsoft Visual Studio 2010; Upgrade license Key (Enter new license key); Complete.

GOOD LUCK !

To everyone who has internet connection. Don't mingle with your registry it's just a waste of time. Set your CMOS clock right then just click on the button that say's "Obtain registry key online" fill up the form(two fields are only required) then the registry key would show up to your screen then just copy and paste it. then everything works fine. sorry I can't post any images I still need to earn more points...

I was stuck for several days with the same problem. Investigating the registry i found several keys in HKCR were i was denied access even as adminstrator. Among these keys were the Licences key. Tried a lot of things to resolve this access problem but could not fix it.

Finally i worked around this problem with a reinstall of Windows 7 - choosing the Upgrade option when prompted to choose between upgrade or a fresh install. Had to reinstall video drivers but all my programs and user accounts survived.

After the upgrade i have access to the HKCR\Licenses again and Visual Studio 2010 starts as expected.
