RIOT 0.3.1 for IrfanView was released but removed shortly afterwards.
An access violation was thrown during program initialization.
That’s why I released a new version 0.3.2 so fast
– plugin: fixed a problem in 0.3.1 with the IrfanView plugin when retrieving configuration settings. An access violation error was thrown.
– configuration data is now stored in the current user’s Application Data folder.
If Riot.ini is found in the Riot folder, it is used only if the current user has write permissions for it. (this makes it compatible with putting Rot in Program Files for Vista)
