The question is really why would you try to install an old version of avast on windows 7 when it supports the latest avast version, avast 6.0.1203.

Not to mention there is little point in trying to track down a problem in an old version of avast when there is a new version that has been out for 8 months. However this problem would be present even in avast6 as there is a missing C++ Redistributable.

Side-By-Side Configuration is Incorrect Error - 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)
