I installed Parallels 7 on my iMac some weeks ago, and subsequently "Windows XP". The programs I installed after that in XP have all worked fine, but now I am trying to install a flight simulator called "Phoenix", which is less than 2.5 GB in size. When I try to install the program, I get an error message "There is not enough free memory to run this program. Quit one or more programs & then try again". However, I can't find anything wrong! There is approximately 94 Gb of free space available on the XP hard-drive, and 1.5MB of RAM allocated. A friend of mine, is running the same program with only 58 GB of free space, and 768 Mb of RAM. Can anybody offer any advise on this problem. Thanks.
