Latest questions about "accurate time clock"

My office is using ATC Client clock-in program on a really old computer. We would like to put it on a different computer here in the office but cannot find the install disc.

When I try to download the program, the screen goes away for a moment; then it comes back and asks me to click to download. It continues just one minute.

I need an update or patch to enable this software to run its payroll (Crystal reports). It worked fine with Windows XP, but there are errors with Windows 7.
