A quick Google suggests that you should reinstall the Microsoft Visual C++ 2005 & 2008 Redistributable Packages.
Make sure you have downloaded and installed all Windows updates also.
Don't know why exactly you'd get that error, however you could use something such as WinRAR instead - right click the .exe file, choose to open it with WinRAR, then extract the contents to a empty folder somewhere instead. Should be able to install it then.
Winrar cannot execute the .exe. I thought it only did zipped/rar'd files?
The file is a SFX archive. Right click the file you've downloaded, choose 'open with WinRAR', and you'll be able to extract the contents just like with any other archive.
Here are the packages that I have installed on my Windows 7 Home Premium install (Windows update did all of this for me). It might be worth checking which ones you have got/have not got by comparison, if only to eliminate it from your enquiries.
