just downloaded Flash Builder 4 and try to install, but installation hangs on at "Installing..." screen. What can cause the problem?
I use Windows XP SP3.
Where did you extract your installer to? There's a known bug where a subcomponent hangs when installing on windows when the path contains a leading space https://bugs.adobe.com/jira/browse/FB-26442.

Even though there was no leading space, it was hanging at the same screen.
I had a hint from the known issue, so I moved the extracted copies into another plain name directory with no spaces.
After that, I could succeed installation without hanging.
