Can't open the PolSARPro

I have been engaged in installing PolsSARPro for nearly two hours but still I cannot open it! I installed all the required software including TCL-TK (using both of those links provided in the Readme file). At the end when I want open it with ActiveTcl, it gives me this error:
can’t read ‘Version’: no such variable
while executing
‘append PSPEnv $Version’


Can anyone please help me with this?
Thanks so much in advance!
