I've played with UniServer from time to time in the past, and just started using the coral series in the last week. Long story short, I've discovered that when I start Apache from a UniServer folder on my desktop, it works fine. If I move it somewhere else (e.g. C:\, D:\), it crashes when I try to start it. Since UniServer is portable, is this a Windows permission or security issue? Am I overlooking something? I'm running Win7 x64 with UAC enabled. Please let me know if I can provide more information. Thanks for your help, and thanks for your great software!
