on win7 x86 google chrome ...
if i use the cooliris icon of coollector the program crash ...
i found an easy way to fix it ...
it's seems an empty folder named "cooliris" is required (where the tmp folder is) .
the installer seems to not create it and the program seems not have permissions or whatever to create it ...
i have just make an empty folder named "cooliris" and now the plug-in works fine

hope this help !
