The log says: The Windows Installer Service could not be accessed this means, that the Service is not started. Type services into the start menu search and run the MMC snapin. Find the Windows Installer Service, make a double click on it and set the start type to automatic and try to install .net 4 again. best regards André"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Even with the Windows Installer Service being set to automatic (and manually started), I still get this error.

Does anyone have any ideas about what I should do? Even with the service set to automatic start, and having it running, I still can't get it to install. I'm really running of ideas.

Nick - Is there a reason that you need Beta 2?The RC version was posted about 2 months ago - http://blogs.msdn.com/jasonz/archive/2010/02/09/announcing-vs2010-net-framework-4-release-candidate-rc.aspx You might want to try that instead. And the VS2010 launch is tomorrow. I'm not on the VS team so I'm not certain of this, but I believe it includes the RTM version of .NET v4.Want to know if your current hardware & software will work with Windows 7? Check out these links: **Windows 7 Upgrade Advisor ** **Windows 7 Compatibility Center**

The RC1 also gives me the same issue. Here's a log from that one. http://cid-b03e0c7ca3db7299.skydrive.live.com/self.aspx/.Public/Microsoft%20^_NET%20Framework%204%20Setup^_20100411^_214922781.mht

Have you tried the RTM version of .net 4?"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

I also can't install RTM. http://cid-b03e0c7ca3db7299.skydrive.live.com/self.aspx/.Public/^5RTM^6Microsoft%20^_NET%20Framework%204%20Setup^_20100413^_180714752.mht What is it with .NET 4 and 64 bit Windows 7 systems?
