Why visual studio 2005 does not work on windows 7?

"Why visual studio 2005 does not work on windows 7?I tried to to install sp1, but the package can not be installed with the following error message:
"The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch."

Tried also to Install SQL Server 2005 on windows 7, but keep getting error message:
"This program has known compatibility issue."

Anyone has some ideas or fixes?

Thanks in advance.

A few suggestions/comments on the setup process:

1) Before starting the SP1 upgrade make sure you first uninstall the standalone VS 2005 Web Application Project download if you've installed that on your system. You'll no longer need this as support for it is built-in to SP1, and the SP1 installer will block and make you uninstall it if you have it installed. Your existing web application project files will continue to work just fine - so you won't need to-do anything to update them to work with SP1.

2) SP1 will run the upgrade patching process on each copy of Visual Studio 2005 it finds on your system. So if you have VS 2005 Professional, Visual Web Developer Express, and Visual Basic Express on your system, it will run the patching process 3 times (since each of these installs have separate copies of some files). If you aren't using all of these versions on your system, you might want to uninstall some of them - both to save yourself some disk space as well as to speed up the SP1 install process.

3) SP1 will patch/update all files/features in VS 2005 that you have installed. Sometimes I just click "install everything" when I setup VS 2005, in which case I get a lot of features that I often don't use (for example: some of the C++ header/lib sources for ATL, MFC, etc). What I've seen on my personal system is that when I only have the features I use installed, the SP1 upgrade process takes about 15 minutes end to end. But with everything it can take closer to 45-50 minutes. You might want to consider unchecking certain features of VS if you aren't using them and want to both save some disk space as well as speed up the SP1 install process
