cant install SIMILE

 Hi, 

I downloaded the free trial version of SIMILE 5.5. Unfortunately, I can't install it in my laptop. I am using Mac OS 10.6.1 (Snow Leopard).

The error says:

Simile error: Simile encountered an unexpected problem: couldn't open "../Run/userinfo.txt": read-only file system

Any assistance will be greatly appreciated. Thank you very much.

Respectfully yours,

Sev
