Simulator not able to allocate enougth memory

First let me just clarify your statement that you have 10 Gb of free memory. Are you referring to RAM or space on your hard drive? I know you are referring to memory (RAM) but I just want to ensure we are all on the same page.

Second you are in fact using a 32 bit product where 32-bit systems are in fact limited to 4 Gb of memory allocation regardless of how much you have available on your machine. On some systems this maximum limit can be even lower depending on how the operating system handles memory allocation. It would appear you are hitting the limit of a 32-bit system. Might I suggest you try the 30-day evaluation of the 64-bit product?

The reason you are not getting access to the full 4 Gb is possibly a limitation within your specific operating system and without heavy diagnostics I would not be able to tell you.

Based on Windows 10 documentation a 64-bit product can access anywhere between 128 Gb and 6 Tb depending on the version of windows you are using. Most Windows 10 systems our users are running are either Home (128 Gb) or Pro (2 Tb).
