Hi there. I have a program that works perfectly well on my XP system. I have installed G77 on my laptop running Vista following the instructions I found on the web. I then complied and tested mytest1.f and it complied and ran without a problem. So I compiled my program which also compiled fine. However when i try to run my program I am getting the message: The System Cannot Execute the specified program. Any ideas how I can fix this? Michael
