hi i'm new to computers. i'm trying to download a game but it gets stuck when its configuring the new software installation then an error pops up stating "error 1330. A file that is required cannot be installed because the cabnit file D:\Defaul~1.cab has an invalid signature. This may indicate the cabnet file is courrupt. Error 24592 was returned by WinVerifyTrust." after i click okay another error pops up saying "Error: -1603 Fatal error during installation. Consult Windows Installer Help (Msi.chm) or MSDN for mor information." i don't know what Msi.chm is so that didn't help. i've had this installed before but i also uninstalled it. can anyone help?
