Reason: This error occurs when using a roaming profile. With a roaming profile the user settings, Application Data, HKEY_CURRENT_USER registry entries, and User environment variables are all transferred to any machine you log into on the network. Since RSM uses network accounts to submit jobs, when you try to send an analysis to the remote solve manager/computer server, your user environment variables were also transferred to that machine. On a Windows computer your user environment variables will overtake the system environment variables. This means that the user variable for a 32bit machine (“ANSYS_SYSDIR=Intel”) was being used instead of the system variable for the 64bit machine (“ANSYS_SYSDIR=winx64”). Workaround: Verify that the following system environment variables are set on the remote machines: ANSYS_SYSDIR ANSYS_SYSDIR32 ANSYSLIC_SYSDIR Then remove the corresponding user environment variables from the client computer. Possible problem: If Workbench is ever reconfigured after these variables are deleted, the Workbench reconfigure will rewrite these variables and recreate the problem.
