cant open avast free version after downloaded

how can i fix this problems?
should i download at program file (x86) rather in program file??or does it matter?

Did you remove your previous antivirus first? Which version of Avast did you download and from where? Here is the current version. Uninstall your version of Avast using the Avast uninstaller.

The - Side-By-Side Configuration is Incorrect Error - is usually associated with not having the required C++ version installed.
You need to install MS Visual C++ 2008 Redistributable.

You need 2008 SP1 - this is the one:
Microsoft Visual C++ 2008 SP1 Redistributable Package ATL Security Update
Note this link there are 64bit versions there (IA64, x64) ensure you get the correct one for your OS (x86 32bit OS, x64 64bit OS)
