Installation of V 1.18.2 stopps while creating "secret key"
Fragment of a discussion from Project:Support desk
The developers had better check to see whether this may result from someone tinkering with the repository... See if re-downloading that or using a trunk version (the latter requires using Git) may work to rule that out.

I also have the same issue on Windows Server 2003. - Hope there is a fix soon.
It's pretty unlikely to be dependent on your OS though...

Actually its probably a Unix vs Windows thing. The method for getting random numbers varries depending on OS (we call mcrypt_create_iv - but it does different things on unix vs windows).
