Avasti 5.0 setup will not Start Up. Ticket 324267234

We have used a free copy of AVASTI on a WIN 98 computer for the last year. The free copy expired. We downloaded the 5.0 setup file into the Programs folder. Also downloaded the License file and copied it into the same folder. When I doubleclick on the Setup file a message appears saying a new version of Windows was expected and I must update my Windows 98 software. The free copy has been running for a year but the setup file that we downloaded will NOT START. Any hints on what to do? We are frustrated and would like to have our amount charged to our credit card refunded if we cannot get this to work. Please advise. Thank you. This was submitted on Ticket 324267235 (March 27) but there has been no response of any kind from any source. It appears our money has disappeared into a big black hole. The computer is unprotected. Any help?? Don

Avast 5 requires WIN2000 or newer.
It will not run on Win 98.

That is stated in the system requirements on avast.com.
You said you used the free version? What did you pay for? Free version is freeā€¦
