"Error loading BMECH entity system" whenever AECOsim is open in ProjectWise
This error can suggest a few things; there might be a mismatch of products (incompatibility between versions of PW and AECOsim), user do not have full permissions or can also mean not enough storage space. These are other aspects of the error message but if the error is happeing to only one or two people in the company but others are not seeying the error check to make sure the settings or setup is the same across all users.
