There are memory requirements for upgrading to version 7 (and version 8). To upgrade a PIX515 to version 7 requires at least 64 MB of RAM. According to your post you have 32 MB. So to do an upgrade you will first have to upgrade the memory. (and depending on your license requirements it could possibly require 128 MB).
