CCSv5.5 Failed to upgrade to compiler 7.4.9

Hello,

I was checking for an update and noticed Compiler Tools 7.4.9 was available, downloaded the package and executed, but I didn't receive any error messages that installation failed yet there is no folder c6000_7.4.9 in \ti\ccsv5\tools\compiler folder and I cannot select it in project settings. Trying to check for an update again it says "No updates were found". Any idea why it didn't update and how to fix the problem? I'm trying to update since I got "INTERNAL ERROR: \ti\ccsv5\tools\compiler\c6000_7.4.8\bin\opt6x.exe experienced a segmentation fault" and "This is a serious problem. Please contact Customer Support with this message and a copy of the input file and help us to continue to make the tools more robust."

Thank you in advance,

David.
