I try to open a model file using erwin r9.7 and I get the error,
If I copy the file and paste it elsewhere like my desktop I am then able to open it.
Please add the write privilege for your windows user or group for the directory the file resides in.
Right-click the directory or file and go into properties. Choose the tab security. Choose the Windows group or user you want. Press edit. Check on the Write checkbox and apply the change.
Now the user should be able to open the model.
