I installed win zip 7. and it was working fine. When I tried to upgrade another program, I got and error message **winzip self extractor winzip self extractor header corrupt. Possible cause bad disk or file transfer error. I deleted my original copy of win zip and tried to download a new copy. Guess what I get the same error code and cannot download anything in zip format. Not even the win zip program. I have tried numerous times to download the win zip program and get the same error code. Can anyone help me with this. Karen Coghlan [log in to unmask] PCSOFT mailing list is brought to you by: The NOSPIN Group http://nospin.com
