Licensing bug fix

Windows : downloaded .zip is 12 MB lighter now, for faster downloads and updates. Our .exe installer doesn't install Visual C++ Redistributable automatically anymore, but it will detect if you need to install them, following our article about it https://www.autokroma.com/blog/VCRedist/

Premiere Pro MultiRender workaround implemented for Adobe markers bug, sometimes the duration of the export was off by one frame. With the workaround it exports the correct number of frames but you can't trust what is written in Premiere Pro markers UI : sometimes the end frame of your marker span will be wrong because this is an Adobe bug. MultiRender now automatically detects the right frame you wanted to export from the clip you selected on the timeline when you pressed the button in AfterCodecs Panel

Installer improvements : it will warn you if the MediaCore folder does not exists, will create it for you in that case. On Windows it will also warn you if you have Adobe applications running while trying to install / update plugins and Visual C++ Redistributable x64 is also automatically installed now

If AfterCodecs is in Trial Mode, it will write a .txt warning you about it in the same folder than your renders

MultiRender : AfterCodecs now avoids exporting markers that are duplicated (for example if you click multiple times on the Add Markers buttons for the same clips, you'll get duplicates)

After Effects : there is now a new checkbox in the Settings to disable AEfx taskbar icon's progress bar feature from AfterCodecs introduced in version 1.8.0

GIF bug fixes
