out of memory error on DPARSFA

I've got some errors while launching DPARSFA on Matlab 2019a on windows.
-I'm trying to run DPARSFA on a single test subject which is about 4 GB (2GB in zipped format) and my voxel size after normalization is 1*1*1
-I've enabled the 3GB switch on my windows
-I've checked the "Automatically manage paging file size for all drives" box off from the "Advance system setting"
