Plugin with Qt UI with 64 bit Illustrator

[Dataset]

- I have developed a plugin with Qt 4.8 UI in Visual Studio 2010 which works perfect on win32 platform.

- I understand, to run a plugin with 64 bit AI, we need to compile the plugin with x64 configuration in Visual Studio.

- Qt 4 + Qt VS addin are incompatible for 64 bit configuration in Visual Studio !!!!!!

- Qt 5 do not support QWinWidget !!!

How do I make my 32 bit plugin to run with 64 bit AI ?

Any option other than interprocess communication ??

How do generally developers do stuff for so many variants of Illustrator ?

1. To run in 64-bit, you'll need to compile & build everything you use with your plugin in 64-bit. That includes Qt and your plugin.
2. We don't use the Qt VS add-in, try using the qmake system; it generates your project and does all the UIC & MOC stuff for you when the project is created.
3. Qt5 is currently a problem for Illustrator development, but hopefully its one that gets solved.
4. Interprocess communication? I'm not sure what you're talking about.
5. We used to build a single plugin that would run in a range of Illustrator versions, but since CS6 came out, we've been forced to build a seperate plugin binary for every version & architecture combination (e.g.,32-bit CS6, 64-bit CS6, 32-bit CC, 64-bit CC) we want to support. We're hoping that at some point we can go back to building one plugin for CS6+ but so far that doesn't seem possible. We're also hoping tha 32-bit just gets dropped soon because 32-bit is a waste of everyone's time at this point
