Standalone 1.70.00 corrupts PATH

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install StandalonePsychoPy-1.70.00-win32.exe
2. View PATH (e.g. execute 'echo %PATH%' on command line)

What is the expected output? What do you see instead?
Instead of appending (or prepending) the PsychoPy2 path to the PATH environment 
variable, it writes over the variable, causing other programs to break because 
DLLs and EXEs can no longer be found.

What version of the product are you using? On what operating system?
StandalonePsychoPy-1.70.00-win32.exe, MS Vista 32-bit

Another user reported something similar a few years ago, in relation to a winXP 
box (I think). But Ive never been able to replicate the problem - my path 
(below) is unaffected by installing and uninstalling PsychoPy 1.71 (on Win7 or 
XP). And I'm guessing is this were happening more widely we'd be hearing fomr a 
LOT of people about it. So the question is what circumstances cause it to occur.

Does it depend on what the contents of the path is? (ie is there some string in 
the list that confuses the installer?) Is your path set in the all-users or 
this-user? Would be good to work out the specifics of when this occurs.

PS, issues are generally now tracked on github, not here.

Is it possible that your PATH variable was previously enormous? Specifically, 
more than 1024 characters long?

I've switched to using a 'long-strings' build of the installer script builder
