I tried installing Intuit’s Quickbooks 2013 today on a Windows 2012 server and received a message advising; “your system has only xxxMB of memory. Quickbooks requires at least 1GB of memory.”
There was most definitely lots of RAM, so fortunately a quick Google turned up the following Intuit site which indicated Quickbooks does not always detect the proper amount of RAM available on 64 bit systems, and proposed the solution below:

However I will elaborate slightly…
Rather than install from a CD copy the installation files to a location on the computer, then locate the following the file; …..\QBooks\Framework.xml For safety sake make a copy of this file, then review the properties of the file, and remove the read only attribute, if present.
Next open Framework.xml with Notepad and locate the memory requirements under <MinRequirements> within the following text.
Change the specification from 1000MB to 0MB, save the file, and re-try your installation.
