Are you sure your installation and setup program got all of the required dependency files?

crviewer9.dll,craxdrt9.dll,crdb_odbc.dll
i was included these files also
what is craxdrt.dll file
is it needed. i find one of the forum thread to include this file
but i was not found in my system this file
is there any other files to be added

any suggestions??

Check this link to be sure you have everything.

thanks hack

Give me the exact wording of the error message and the error number.

sorry hack i missed the error number
i will give you the error number when i run the program in client system.
now i can't run the program in client system.
error messge is query engine error ,can't find dsn connection string.

i think the problem is when ever i run the report it is asking for data source and password. everytime when ever i try to run the report individually (not from vb) it is asking for data source and password.
is it a problem

thanks hack
