Just thought I would pass along something that I could not find in a search, but eventually discovered myself. I just got upgraded to a new PC with Win7-64bit, and even after installing the LV2010 runtimes, device drivers, etc., even the simplest compiled LV .exe application (a toggle switch connected to a light) would not run. Windows was no help, just saying that the program caused an error and was being closed. Eventually I checked the Event logs, and found the issue was related to a file named niwebserver.conf. Long story short, a few years ago I was experimenting with remote panels, and had turned on the Remote Panel Server (Tools -> Options -> Web Server -> Enable Remote Panel Server). The experiments were abandoned, but I never turned the server off. It turns out the configuration file generated (niwebserver.conf) is incompatible with Win7-64. The best solution is to recompile with the server disabled. If not possible, and remote panel is not being used, try deleting the niwebserver.conf file, as this will sometimes work.
