Just discovered that Flash Builder 4.6 and 4.5 do not run. Flash Builder 4 does. Get the logo popping up but nothing loading. I'd uninstall the other two versions but I get an error when I go into my program settings and click on my CS package.
Moving this thread to the Using Flash Builder forums.
UPDATE: I contacted Adobe yesterday and they had me do something I would of not thought of.
On the Services tab click Hide all Microsoft services.
Click Disable all button
Restart your system
Run Flash Builder (It now started)
I closed Flash Builder and went back into MSCONFIG
Uncheck Hide all Microsoft services (if checked)
Click Enable all button
Restart your computer
Flash Builder still worked after this. All is now good.
