I am using ********** to install my app on a Vista machine and with the line:

Code:
Source: C:\Documents and Settings\new folder\msado25.tlb; DestDir: {sys}; Flags: uninsneveruninstall sharedfile regtypelib;
I get the following error on trying to open the App after the install and re-boot which goes OK.

c:\windows\system32\msado25.tlb
Unable to register the DLL/OCX:RegisterTypeLib failed;Code 0x8002801C

Any idea's what I am doing wrong ?
