Dear sirs, after the software installation,
I run one time the eprom programmer TOP2005+ it will install the hardware and after I can open the program. After I try to program an eprom but I doníread the same checksum declared by eprom software developer.
So I think there was a problem on the file type setting ( hex or bin file). I see there was no chance to delete the checksum buffer so I exit from the program and run it again.
But when I try to open I receive the following message after initialization wiondow:


Error message,

access violation

access violation at address 74DE0CC2. read of address 74DE0CC2.





May you help me to solve the problem.
I try also to uninstall and reinstall the program and the USB driver but without any results.

Waiting your answer
Best Regrads,

Federico Brunoro

The checksum:
Open the file, you will see the checksum at the lower-left cornor.
Once you programmed the chip, read the chip shoule give the same checksum. Otherwise your chip is not programmed correctly.

For the error message, please see:
