ActiveX component can't create object

Hi,

I have an issue with one of the customer machine that is when I try to install the application it gives the 429-ActiveX component can't create object error.

I tried register vbscript.dll and scrrun.dll on both system path and app path but no success. It is a XP professional OS SP3 installed. My application worked before on the same machine and the customer did some changes because of the virus attack of his machine. After the change gives the error in my app.

I found the code where it gives the error here is the code

con.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & SpecFolder(CSIDL_COMMON_APPDATA) & "\" & workingdirectory & "\TestDb.mdb"

Please advise me.
