I must report a bug with the July and December 2013 releases of Supremacy.
Most of the time games cannot be saved.
Game log reports an "Out of Memory" exception.
DETAILS:
Supremacy is stored in D:\Games; full permissions there.
(Game save path is, unchangeable, C:\Users\XXX\AppData\Local\Star Trek Supremacy\Saved Games\ )
Computer has ONLY an Admin. account.
Starting Supremacy as Admin works at first, but after a while autosave
stops and manual save is no-go.
Restarting game (again as admin) is good only for one save or two; like
a tightening noose the range shrinks.
Running in WinXP compatibility mode also is in vain.
Running thru a virtual XP setup gives a startup error.

I run Windows 7 Ultimate sp1, 64-bit. with NET 4.51; 32GB system RAM.
Virtual memory ~49GB.

Last entries of Game Log are:

i have no idea to that atm, but do you have a save game for us?

The game is apparently running out of memory to successfully save.

How much RAM does your PC have and can you verify through the task manager how much memory Supremacy is using when it's running (just before you try and save)?

he's underway with superluminal velocity, but maybe that's exactly the problem of too much RAM (too less RAM can not be the problem )

Thx reg, didn`t notice he mentioned it already

A couple of questions:
Did this also happen before the july release?
Does it happen for all map sizes, or for which does it start happening?
Does it happen with and without minors?
Any other information that might be relevant, like ship count, colony count, etc that you find to trigger this?

Thanks

In answer to latest query, no such save error with pre-07/2013 releases; but in all fairness I must state thah previous releases were played under a 32-bit Windows system (XP sp3).
This leads me to ask: is Supremacy a 32-bit program?
I have learnt that 32-bit systems (and presumably PROGRAMS) cannot access memory above 4GB.
Second, 64-bit apps tend, unit for unit, be larger and use more memory than 32-bitters do.
The 'Out of Memory' issues crop up once memory usage has hit roughly 11-13% (which out of 32GB gives arrrox. --4 GB-- consonant with presumed limit of memory access for 32-bit apps).
If Supremacy IS 32-bit; know of any way to make it see memory above 4GB?

Forgot to mention; I usually max out galaxy size and number of minor races. Usually start at early tech level.

I assume it's 32bit, but running on a Win64bit system should work as well.

But maybe just start Supremacy using some windows compatibility mode (via click right mouse key) ...and please tell us when you had success in any way. Thanks and good luck
