When opening AECOsim Building Designer I get the error “Data Group System - XML Error: Error Parsing: MRU_Lookups.xml”. Why is this error happening and how can I fix it?
The XML was either changed, contains bad data or it is missing. Locate the .xml following the path indicated in the error message and replace the MRU_Lookups.xml with a new one, acquire the file either from another colleague in your office or you can also use the one below:
MRU_Lookups.zip
