Error running SpywareBlaster

Hi everyone

I tried to install SpywareBlaster on an old PC and got the following error:

Error while unpacking program, code 4. Please report to author.

I've searched the knowledgebase, and cannot find any reference to it.

I've tried downloading the installation file from three different websites, and all three give the same error.

MY PC configuration is:

AMD Duron, 384 MB RAM, 14 GB hard disk, SIS 315 video card, Windows Me.

My internet connection is 2.2 MB ADSL broadband.

The other security software I'm running is ZoneAlarm 3.1.291 (I'm running the old version because the current version will only run on Windows XP, and this PC isn't up to running that), AVG Free anti-virus 7.5.432 with latest updates, and Spybot Search and Destroy 1.4 with latest updates.

Any help would be very much appreciated.

Regards and TIA,

Rob.
