Memory error in polsarpro

I am new to Polarimetry and PolSARPro. I wanted to do polarimetric decomposition and generate c2 matrix.
I have installed PolSARpro (Version5.0) and started using. In the first step I gave my Sentinel-1, SLC product as input with single swath, all bursts. But I have encountered the following error. “not enough memory space”.

I did’nt understand how to change processing memory. Also please guide me through next steps.Please help me and thanks in advance.
PS:I am using 32 GB RAM with 1TB hard disk space
