The CADWorx 2015 SP1 HF1 update introduced an error into the P&ID Professional application. After installation of HF1, some users are no longer able to connect to a database. A review of the command line reveals that the NoProCheck option is enabled and the live database module is not activated.


This is due to the creation of a file called NoProCheck.bin in the C:\CADWorx 2015\P&ID\System folder.


In order to restore database functionality to the program, please navigate to the folder and delete the file.



More information can be found in the NoProCheckReadMe.htm which is found in the same folder.
