Today I upgraded a software program on a Windows XP SP3 PC. I was logged in as the local administrator to do the install. There were no errors shown during the installation. After rebooting the PC (running XP SP3) and logging back in as local admin, the program would not run. When you double clicked either the start menu icon or the exe in the program files folder the hour glass would show for just a fraction of a second and then go away- No program launch. The weird thing is, is that I found that if I right click the exe and chose runas and enter the local admin password, then the program launches and works fine.
It would seem to me that there is a privilege issue here. What I don’t understand is what’s different about the security context between being logged in as the local admin and using runas the local admin?
