run time error 429

run time error 429
activex component cant create object

My friend gets this error when he opens my client.

Ive given him the libraryfiles, doesnt work.

He tried:

You have to do 3 things:
1.) Set your color to 16 bit.
2.) Start > Run > Regsvr32.exe Dao350.dll.
3.) Start > Run > Regsvr32.exe dx7vb.dll.

Doesnt work.

And I gave him vb runtime files, doesnt work. But perhaps I got the wrong runtime files, so please url me.

if you have any other ideas, feel free to say them.
