When Zone Alarm is installed on the computer it loads on the initial install. But attempting to open Zone Alarm via the taskbar, shortcut, or directly from Start does nothing and program won't open. It still shows in task Manager. Other programs also start failing to open after ZA starts having this problem.
System: I've done a complete hard drive wipe (deleted partitions and full reformat) and then installed Windows XP and all updates to SP3. I've had hardware diagnostics done to rule out hardware issues.
AVAST! Anti-virus was downloaded from another computer to a virus-checked thumb drive and installed. Zone Alarm was installed the same way. At this point there was no problem.
A restore point was set in order to be able to troubleshoot.
I then installed Firefox via thumb drive . Zone alarm would no longer open, nor would Firefox. I uninstalled Firefox but that did not fix the problem.
I then went back to the restore point. After the restore I uninstalled Zone Alarm. I then installed Firefox. Everything worked fine. I then installed Zone Alarm. Since I am not internet connected the Toolbar could not be loaded. I continued anyway. Completed with 503 programs scanned. Did a restart. Zone Alarm and Firefox both fail to open.
In Task Manager/Processes I cannot end either firefox.exe or zlclient.exe. Nothing happens when I try to end the firefox process, but I get a "Denied" message when trying to end zlclient.
I could try other program installs but Zone Alarm appears to be the one program that always causes the failure.
