installation failure(CCS5.5)

When installing, I get the following error message.

Install Verification:


Installer failed to install com.ti.cgt.c6000.7.4.win32 correctly.The 2 most common reasons for failure are:
1: Anti-virus on your computer could have impeded the executable.
2. Download is corrupted.

The install log ends with the following:
