I noted this topic from May 2012 because I am having the same problem...new computer...new FSX and Rcv4 install and I am getting an "error 7 out of memory when I try to load an FSX flight plan.
I noticed in the pass thread that the topic stopped with the user getting a solution. I have tried all of the internet solutions for error 7 problems I can find without any resolution.
Does anyone know of the cause or if it is because of RCv4 or a Win7 memory problem?
Any and all input will be greatly appreciated...I think this program is great and flighing without it will be a great loss.
