Hello, anyone from Adobe? I actually do need an answer...
There was an issue regarding permissions.
Can you check if you have admin rights (if you are on Vista/Win7) and if the FBInstalldir/plugins is read-only?
Thanks for your reply, but unfortunately I have not yet resolved the issue.
On Mac OSX I changed permissions of the plugins directory, and also ran FB as sudo. Still not working.
This is happening for me on Vista and OSX. It is happening for my co-workers on XP. All of us have the same issue of not being able to use the "Install New Software" feature. We all have licenses for our FB installs. I think all of us started in the FB4 pre-release program, but when FB4 was released, we got the trial version, then bought the licenses and entered the license numbers.
Here is a screenshot:
I think you might be experiencing this issue because there are no default Eclipse update sites defined in Flash Builder.
Please see this blog post for more information on how to resolve the problem: http://blogs.adobe.com/jasonsj/2010/03/installing_plug-ins.html
Senior Product Manager, Flash Builder
I found the answer to my issue when I could no longer start Flash Builder. All I got was a message box saying "Licensing for this Product has Expired", even though my license is perfectly valid. A Google search found this document: http://kb2.adobe.com/cps/494/cpsid_49485.html
Although the article is for CS4 & CS5, it appears to apply to Flash Builder as well.
I followed Solution 3 - uninstall Flash Builder, delete some directories, re-install Flash Builder, and put in my license key.
This likelly occurred because I was part of the Flash Builder 4 pre-release program, and I had installed many version of Flash Builder on my Mac. I always uninstalled the old version first, but things got hosed up anyhow.
After following Solution 3 in the Adobe doc (link above), the problem I was seeing with Install New Software went away. Hopefully, this helps someone else.
On Mac OS X 10.6.4. I could not install new software/plugins because Flash Builder prompted me that I had no Administrator privileges (although my user account had Administrator privileges).
The solution was to change permissions in the Application folder of Mac OS X: I added my user account in the bottom of the properties window of the Adobe Flash Builder 4 folder in the Finder and gave read/write permissions to all folders and files within the Adobe Flash Builder 4 folder...
