Hi all,

my client have a program i wrote that connects to a database at start, for the past few months the program worked fine no error what so ever, and i gave them a newer version of the program and when they used the new .exe file they got the "runtime error 2147467259 (80004005) Cannot open database requested by the login. The login failed" Then they tried to use the previous version of the program and the error still occur. The update i did for the two software have nothing to do with the connection string, is basically some operation upgrade. In addition, it works fine on my computer. I am really confuse in what might be the cause of this error. If anyone can give me any suggestion it would be great. Great thx
