BACKTRACK Import or Restore Stops with ‘Out of Memory Error Message’ – BACKTRACK Problem


This article explains the problem of BACKTRACK Imports and Restores stopping and throwing an ‘Out of Memory Error Message’ and provides advice on how to get around it.


The BACKTRACK Import or Restore stops before completion and ends with a ‘System.OutOfMemoryException’ error message.

From an Import:

From a Restore:


BACKTRACK cannot access sufficient memory to complete large Import or Restore operation.  Both operations can be very RAM intensive.  As a 32 bit application, BACKTRACK is limited to the RAM it can access even if the computer has the RAM available.


There is a Windows patch that can allow BACKTRACK to access more RAM.  The patch is attached.

Here is a description of the patch from the site:

“I originally wrote this tool for a friend of mine who needed it. This very little tool patches x86 executables in order to let them have 4GB (instead of only 2) of virtual memory on x64 platforms. This tool comes very handy for applications which need a great amount of virtual memory like games, 3D renderization, multimedia etc. To gain these 2GB, you just have to use this tool to patch the executable (*.exe file) of the software you want to have these additional GBs of virtual memory. It can be used by clicking on it and choosing the file or through command line (e.g.: “4gb_patch file.exe”). It automatically creates a backup copy of the original executable.”

“Why things are this way on x64 is easy to explain. On x86 applications have 2GB of virtual memory out of 4GB (the other 2GB are reserved for the system). On x64 these two other GB can now be accessed by 32bit applications. In order to achieve this, a flag has to be set in the file’s internal format. This is, of course, very easy for insiders who do it every day with the CFF Explorer. This tool was written because not everybody is an insider, and most probably a lot of people don’t even know that this can be achieved. Even I wouldn’t have written this tool if someone didn’t explicitly ask me to.”
