MSSQL without installing MS SQL Native Client on the Client Machine

Hello,

i would like to avoid installing the MS SQL native client on the client machines. But installing the sqlncli.dll/rll/chm files only will not work because “the client does not support encryption”.
I did some research and found many Registry entries which seem to be needed to make it work. Is this true?
Is there no way to add a few more files to my Xojo App Setup which would make it work without those Registry settings?

I could add those entrys with my InnoSetup Setup but i really would like to avoid modifying the clients Registry Database.

BTW: I use the MBS MSSQL plugin for the connection.

Thank you in advance!
