MSI Studio was updated in ChangeBASE v.6.2.2, however this update introduced some undesirable side effects in its operation.
To remedy this, Development have rolled back MSI Studio to the last stable release.
If you have not updated MSI Studio then there is no need to make any change.
If you have updated any packaging machine with MSI Studio v.188.8.131.52, then use the ChangeBASE v.6.2.5 installer (and select the relevant option) to update your MSI Studio instance.
Fix appears in ChangeBase 6.2.5
