Thank you for this help. I downloaded/installed daemon tools and was able to reinstall Quake w/o previous displayed errors & delayed time. It started but required the DVD disk, and tells me to put it in the drive and restart the application.
I will read over Daemon Tools on how to use it with iso files so that I can run Quake. But if you can help me with those steps I would greatly appreciate it. What I did do was, re-installed Quake, then Mounted the iso on a DVD-RW disk. But haven't been able to get Quake to run from my desktop icon w/disk in drive.
Using Daemon Tools (DT) and having mounted Quake as a virtual drive (if correct because I see it in My Computer), through DT when I run Quake.exe I get, "library not registered" and the OK button doesn't work - I have to use the X to close the window. At this point another window tells me that Splash Screen has stopped working. This is as far as I have been able to get with Quake.
Thanks for your help. Of all the thousands of games, Quake is the only one I play. By the way, I am running Win 7
