cannot install visual studio 11 preview [closed]

Question

I use vista sp2 and have vs 2005/8/10 installed.

I try to install vs 11 preview using the web installer but immediately get a message "setup blocked" (see image). the linked log just has many lines like

[1424:1894][2011-09-17T22:13:51.749+02:00]: Detected package: netfx_dtpmsi_1048, state: Present, cached: No

any idea?

Answer 1

I believe Vista is not supported by the Visual Studio 11 Preview; the published system requirements are different from all of the internal messaging. You need Windows 7 or newer. I recall that older systems haven't been supported on internal builds for the last couple months.

(Full disclosure: I work on one of the Visual Studio teams.)
