I have heard from a couple of customers who have uninstalled beta versions of Visual Studio 2005 and then installed the final release. After installation finished, they saw a small error dialog that looks like the following when trying to launch the Visual Studio 2005 IDE:
Pressing OK on this dialog dismisses the IDE and VS 2005 is not usable.
There are a couple of cases where registry data can be orphaned on the machine that causes this type of error. Unfortunately, because this data is written by a custom action and there are some "interesting" conditions on that cusotm action in the VS MSI, running a repair of VS 2005 will not correctly fix the registry values that control this functionality.
The following steps can be used to resolve this Invalid license data error message:
After doing this, the license data should be recreated and correct and allow you to launch the VS 2005 IDE.
<update date="10/25/2006"> Added some more licensing registry values and a new section for 64-bit registry values that need to be removed </update>
<update date="8/27/2009"> Fixed broken link to image. </update>
