[Qt-creator] Making an installer of Qt creator plugin on Windows

[Artem Razin]

Oh, got the point!

Regarding the idea of installing to
%LOCALAPPDATA%\QtProject\qtcreator\plugins\X.Y.Z, will it work if both
32-bit and 64-bit of Qt Creator of the same versions X.Y.Z
installed?.. It seems that no and I again have to return to the task
of detection of all installed Qt Creators.
