Hi.
I'm writing a program in XE4 and the Exe file was running on XP or 7. But when I added a ClientDataSet to the form, the Exe file is running only on the computer taht the XE4 is installed on. In the other computers an Access violation error appears and program is not running.
This not due to the MIDAS.DLL file.

Thanks for any suggestions.

Why do you say it isn't due to midas.dll? It's sounding pretty likely if the errors started occurring after you added a TClientDataSet.

Hello Behrooz,

  do you have midaslib included in the uses clause? If not, I suggest that 
you do so as your problem may relate to incompatible or missing midas.dll 
file. With midaslib in the uses section you no longer need to worry about 
deploying the dll.
