Error Message: Unable to open message file: PROMSGS This error typically arises when the Progress PROMSGS environment variable is not set. If you are receiving such errors, follow the guide for your driver architecture -- Multi-Tier Drivers Use a text editor to open the active Rulebook (default, <OPENLINK_INSTALL>/bin/oplrqb.ini). Locate the [Environment PROGRESSXXX] section which corresponds to your database agent. For example: [Environment PROGRESS82A] DLC = C:/Pro82aDLC Path = C:/Pro82aDLC/BIN;D:/WINNT/System32 ;PROMSGS = C:/DLC Insure that PROMSGS is uncommented (no leading semicolon, ";") and set to the full path to your local promsgs file. For example: [Environment PROGRESS82A] DLC = C:/Pro82aDLC Path = C:/Pro82aDLC/BIN;D:/WINNT/System32 PROMSGS = C:/Pro82aDLC/bin/promsgs Save your changes and exit the file. Restart your Broker and test. Single-Tier Drivers Open the System control panel. Set the variable on the Environment or Advanced tab. If you have a choice between System and User variables, set this under System. For example: PROMSGS C:/DLC/bin/promsgs If you do not have the System utility, you will need to set PROMSGS in your autoexec.bat. You will also need to reboot. Here is a sample autoexec.bat entry: set PROMSGS=C:/DLC/bin/promsgs Test.
