Invalid license data. reinsall is required....

[Hotshot]

Look like I going to have restalled the windows to fixed that  as I have been checking out the Visual Basic 2010 Express but it wont let me play it as keep saying "Invalid license data. reinsall is required" as I already restalled to fixed that and now it keep asking me that again...

So frustration!  Me Vs Mircosoft  LOL

Sounds like a screwed registry to me I had the same problem a long time ago and this is what I did
Uninstall just the main VB leave all other bits where thy are then from the command prompt paste

reg delete HKCR\Licenses\21B7CDC0-21A6-4fa8-8CE5-F6A6B2B60839 /f
reg delete HKCR\Licenses\2AC5863D-48B9-490c-ACD3-B7723A1FEB9E /f
reg delete HKCR\Licenses\45D0AA33-5564-4a89-BE94-C1972EF4658C /f
reg delete HKCR\Licenses\46D504D7-557F-4C19-A4DD-6605411EF496 /f
reg delete HKCR\Licenses\743A8267-4958-460e-B757-7110EED3D53C /f
reg delete HKCR\Licenses\82198EB8-0FAB-4b2b-98AD-F745A8566EFE /f
reg delete HKCR\Licenses\AEA64E56-7C97-4a1c-8974-4E0BB4E48FCD /f
reg delete HKCR\Licenses\B2825A63-A482-4032-80E6-42C9D2C1A78B /f
reg delete HKCR\Licenses\BA32367F-28F8-4AEA-848D-95AE438B3B9C /f
reg delete HKCR\Licenses\F2E1F428-5B9A-4a69-B1F4-28C3C644168A /f

This then should sort it out no need to reinstall Windows.

I know about MS Dos as I used do that yonk ago and I still remember them(Not sure about the Reg bit). I try do what you put but it seem that cant find the files that I want to delete(i.e.  reg delete HKCR\Licenses\21B7CDC0-21A6-4fa8-8CE5-F6A6B2B60839 /f and so on)



What should I do? 

[Pot Noodle]

What OS are you running?

[Hotshot]

Window 7 Ultimate

[Pot Noodle]

Hi Hotshot,

Windows 7 still uses the Reg.exe file found in your System32 folder.
So I would check and make sure it is there, if it is there, from the command prompt type
C:\Windows\System32\Reg.exe /? and see what it does.

All so make sure you have full privileges to the registry.

Or try this if you know the registry well
Open Regedit and make a backup of your registry first
Then search for the keys and delete them manually.

Hope this helps.

Hi mate,
As you have found it, now you can run these.

reg delete HKCR\Licenses\21B7CDC0-21A6-4fa8-8CE5-F6A6B2B60839 /f
reg delete HKCR\Licenses\2AC5863D-48B9-490c-ACD3-B7723A1FEB9E /f
reg delete HKCR\Licenses\45D0AA33-5564-4a89-BE94-C1972EF4658C /f
reg delete HKCR\Licenses\46D504D7-557F-4C19-A4DD-6605411EF496 /f
reg delete HKCR\Licenses\743A8267-4958-460e-B757-7110EED3D53C /f
reg delete HKCR\Licenses\82198EB8-0FAB-4b2b-98AD-F745A8566EFE /f

reg delete HKCR\Licenses\F2E1F428-5B9A-4a69-B1F4-28C3C644168A /f

Just copy & Paste them in to your cmd window, all should be well!

[Hotshot]

eh?  what does this mean?

[Pot Noodle]

OK First you must open command prompt window.

Then type "cd C:\Windows\System32"

Your command prompt should look like this "c:\windows\system32\"

Then type "reg delete HKCR\Licenses\21B7CDC0-21A6-4fa8-8CE5-F6A6B2B60839 /f" and so on.

it wont let me delete it

[Pot Noodle]

Did you uninstall Vb first?

[Hotshot]

Did you uninstall Vb first?

Yes but it wont let me delete it as I still got the same message above picture that i gave ya

[padman]

Well, if the key isn't there it can't be deleted. If you are on a 64 bit system (if I recall correctly I think you are?) try this instead:

[EDIT] Okay scratch that, I think it was someone else who got a 64bit Windows. 

Anyway, maybe the license keys are only valid for MS VS2008 and not 2010!?

[Hotshot]

Mine is 32 bit window 7 at the moment.....

when come to this xmas....I will be upgrading my Laptop

[Hotshot]

I can install Express 2008 and run no problem where Express 2010 wont let me play it....

[combatking0]

it wont let me delete it

This may be down to administrative permissions.

Try clicking on the start button, then typing cmd into the "Search programs and files" box, then when the search results return "cmd.exe" in the programs listing, right click on it and choose "Run as administrator".

Then try Pot Noodle's suggestion again. If it doesn't work, I'll look into it further.
