Vista directly upgrades Win7 causing problems with VS2008

On weekends, I upgraded my books from Vista to Windows7. The reason for choosing to upgrade is that I don’t want to reinstall drivers, vs, sql, etc. I am lazy and chose to upgrade. The upgrade time is still tolerable. . In the process of upgrading, Windows 7 self-tested some programs that are not compatible with it, such as several programs that come with Thinkpad, iTunes, and the last thing you want to see is Sql Server 2008. Anyway, no matter what, upgrade first, then upgrade and find a solution.

After a night of tossing (the computer is on, I slept), I got up in the morning and looked at the computer. After some simple system configuration, I entered the system interface. It was not bad. There was no other error. I will try every software, Office, Sql Server 2008, Chrome, SaaYaa, Fireworks, etc. There is no problem, my heart secretly hid. However, when I open VS2008, the following error message pops up, please see the picture:

I guess this error occurs because the hard disk space is insufficient during the upgrade. I deleted it. Some C files in the Program Data file, there is no way to let my hard drive split small, 40G partition is not enough. There is no way, only google search has no results, luck is not bad, really let me find a solution, here again thank google, and foreign cattle. Just enter a sentence on the command line, of course, you need to enter the command line program as an administrator, execute the following statement:

Run "%programfiles%\\Microsoft Visual Studio 8\\Common7 \\IDE\\devenv.exe" /setup

After executing this sentence, the problem is solved.

The purpose of writing this article is actually two:

1, Vista Ultimate can be directly upgraded to the Windows7 flagship version (this nonsense)

2 In the event of an upgrade, VS2008 cannot be opened due to the lack of Application Data Folder. You can use the above sentence to solve it.
