I have an .iso file which UltraISO cannot open. It gives this message instead:
ERROR Class name: TfrmMain Error type: EAccessViolation Message: Access violation at address 005EE3E6 in module 'UltraISO.exe'. Read of address 00000000
This happens either with the .iso file itself or with the working CD which was burned from this .iso file with Padus DiscJuggler. The CD is totally functional.
I can open this .iso file or CD with Magic ISO Maker v5.0, WinISO v5.3, and IsoBuster Pro v1.8 without any problems.
I have tried UltraISO on quite a few other .iso files and CDs without any problems, so I believe the installation is OK.
I hope you can fix this because except for this problem UltraISO is better than the other programs I mentioned.
