My Setup program corrupts my ocx files!

My program uses mscomctl.ocx so naturally I include this file whenever I create setup disks using the deployment wizard. The problem is that whenever I try running the setup program, the setup seems to corrupt my mscomctl.ocx. My setup fails to register mscomctl.ocx. Whenever I try running VB6 again, it tells me that either my file is missing or is corrupted. When I try looking at the file size, the size is now 11kb as compared to the old size of about 1Kb. Can anyone help me with this problem?
