SL 2015 CU2 -- "Unable to open the message file ..."

Posted on by 45

We recently installed Dynamics SL 2015 CU2 on a server machine, and also installed a client on that machine. We then installed clients on two remote machines. The client on the server machine works fine. The clients on the two remote machines produce an error message box when starting the program. The message box says that the program cannot find the messages file. The message box is the following:


Any help would be appreciated.

    Butch, Thank you!! This solved an issue I was facing after I upgraded a client to CU2.  It wouldn't prompt me to login, instead it brought me right into Dynamics but the menus were all messed up showing 010111, etc.

    CU2 breaks the reg entries telling SL where it can find its executables.

    Load these keys into the registry after changing the path to where your SL files are:

    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Solomon\Solomon IV Tools For Visual Basic]
