Installshield Problem

[a1]

I can't install the Patch for Cod:Waw 1.2 iwth the installer provided.


The error is 1628: Failed to Complete installation.


i have tried every trouble shooting method to this problem and cannot get it to extract and install. I have redownloaded it from several different sites and still I cannot extract the files.

I need a solution to this problem.


Thanks
