I reuploaded a new version of RC 2 about 30 minutes later with this problem fixed.
I'm not sure if videohelp got this new version yet.

Try re-downloading RC 2 and give it another try. :)

Thanks for the RC2 release. But when I update to 3.0RC2, I can't launch the IcarosConfig.exe, it didn't display the main window.
Do you have any idea? When I roll back to RC1 and everything is fine. Windows 10 x64

Thanks for the feedback, Neroldy. I appreciate it.
I'll be sure to forward this to the translator.

Great tool! Thanks for the nice work!
But there is a little mistake about the Chinese translation, is that "ui settings" translation is not "介面设置", the correct one is "界面设置".

I downloaded this program and had a lot of problems with it. Icaros did indeed generate thumbnails for all of my video files as advertised but it didn't always seem to play nice with Windows 7. On numerous occasions I would open a folder containing video files and the screen would lock up while Icaros was generating icons--I would get a swirling circle in the folder for several minutes or more before I could do anything. This did not happen every time I opened a folder with videos but it became enough of an issue that I finally uninstalled icaros--and all of my problems with the folders went away. I liked having thumbnails for everything but not at the expense of the computer freezing.

Great Tool!!!
I tried a lot of other tools for displaying thumbnails for mkv and flv files.
But I didn't found a working tool. E.g. I tried Haali Media Splitter but this tool created some black thumbnails and other were completly white.
With Icaros I can even display thumbnails for .vob and .flv files.
Thanks for programming this masterpiece.

Installed and seems to work fine/stable. Allows me to get thumbnails in Windows Explorer for FLV files when I couldn't get them before. Requires you to install the LAV filters. So if you have the Haali splitter installed, you will need to uninstall that first.
