View Software Won't Open

Software won’t open; Login allowed but closes immediately

Registry value for screen position may be corrupt: double-click icon while holding shift key until login is displayed.

If HWeb Agent was running fine and then suddenly will not open, and you have tried the above, it may be because the computer was recently upgraded with a Microsoft Windows Service Pack.

When certain service packs are applied as an update to Windows, Data Execution Prevention (DEP*) may be automatically turned on.  With DEP turned on our other products (Dispatcher, Admin) run but not the Agent.
In order to correct this open the PROPERTIES of MY COMPUTER.  Select the SETTINGS button in the Performance Section of the ADVANCED tab. Then select Date Execution Prevention tab and check the first option: “Turn on DEP for essential Windows programs and services only.


* Data Execution Prevention (DEP) helps prevent damage from viruses and other security threats that attack by running (executing) malicious code from memory locations that only Windows and other programs should use. This type of threat causes damage by taking over one or more memory locations in use by a program. Then it spreads and harms other programs, files, and even your e-mail contacts.

Unlike a firewall or antivirus program, DEP does not help prevent harmful programs from being installed on your computer. Instead, it monitors your programs to determine if they use system memory safely. To do this, DEP software works alone or with compatible microprocessors to mark some memory locations as “non-executable”. If a program tries to run code—malicious or not—from a protected location, DEP closes the program and notifies you.

DEP can take advantage of software and hardware support. To use DEP, your computer must be running Microsoft Windows XP Service Pack 2 (SP2) or later, or Windows Server 2003 Service Pack 1 or later. DEP software alone helps protect against certain types of malicious code attacks but to take full advantage of the protection that DEP can offer, your processor must support “execution protection”. This is a hardware-based technology designed to mark memory locations as non-executable. If your processor does not support hardware-based DEP, it’s a good idea to upgrade to a processor that offers execution protection features.
