I am trying to install FB 4.5 as Plug-in, and I could only find Standalone installation from Adobe.com. The standalone download page refers a link, Release Notes, that contains information on Plug-in installation, but the Release Notes results a 404. This has been going on for the past two days. Please help.
By searching "4.5 Release Notes" in Adobe.com, I was able to locate the Release Notes
However, the link to Release Notes at FB download page ( https://www.adobe.com/cfusion/tdrc/index.cfm?product=flash_builder ) is broken:
I just went through this and figured it out and also couldn't find any resources on it. Basically download the stand alone flashbuilder 4.5 and then use the plugin utility in the utilities folder. Works great! http://joeygutierrez.wordpress.com/2011/05/04/flash-builder-4-5-plugin/
The Adobe Flash Builder 4.5 Plug-in Utility is located in Adobe > Adobe Flash Builder 4.5 > utilities directory on your computer.
