I just installed Titanium Studio and checked for all necessary updated.
Help -> Check for updates
Help -> Check for Titanium updates
After running the "Check for Titanium updates" I always get an error message that installation failed and to see the log file for details.
I viewed the Log files to see details...
Help -> Studio -> Log File
I found the following message:
!MESSAGE Error encountered during update !SUBENTRY 1 com.aptana.js.core 4 0 2013-05-31
Apparently, there is an issue with node.ACS CLI.
npm ERR! missing: acs@*, required by undefined@undefined npm
These are the highlights from the "Diagnostics file"
Help -> Studio -> Run Diagnostic Test...
