We do work for a DOT and they still have a number of projects they want us to finish in SS10. It's a contractual thing. We have some users that will open these files in ORD and there is a dialog that asks if you want to brand your file with a workspace/workset, but is does not give you the option to open it in Read Only mode. So we have to make requests to the DOT to restore old versions of the file and it is upgraded to ORD and the SS10 file is still the one needed for work. I have searched high and low for a variable. We have tried the variable CIVIL_UPGRADE_PROMPT_OFF =1 but that only works for versions of ORD. Is there some variable to force ORD to open SS10 files as Read Only? Thanks
