I'm using the offline Windows installer on XP 32-bit, and I have no anti-virus installed.
I had CCS 5.1 installed and tried to update that to CCS 5.4, but that failed. It stalled during the MSP430ware installation, so in the end I had to force-quit it. Unable to launch CCS due to the "The Ccstudio executable launcher was unable to locate its companion launcher jar" error, I took the advice from http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/272593.aspx to delete the CCS files and try a new install. This didn't go so well either. It looks to be going fine until installing MSP430ware, after which it fails, and then there is no CCS directory, so nothing for it by spending another hour trying to install again. Then I tried the installer without checking Grace or MSP430ware, and now the install succeeds. So apparently something is wrong with the MSP430ware. The log file suggests a CRC error (see below). With a working CCS 5.4 install, I then installed the stand-alone Grace, which includes MSP430ware. So I have everything installed and working now, but no integration of Grace / MSP430ware in CCS 5.4 which is a minor nuisance.
As far as I can tell, there is a problem with installing Grace from the CCS 5.4 installer, so you might want to look at that. Actually, it would be quite nice if you took a long look at the whole CCS install procedure, which take forever to do, and often results in errors requiring a re-install. Several times now, I have spent hours and hours trying to get CCS working. I am seriously considering using something else, just with the knowledge that the next time I have to update something it will probably break everything. Again.
This is an interesting bit of the log, which indicates the problem to be a CRC error:
