Re: component "qt" missing
Where did you get that application ?
if it is your own, then do check the materials on Smart insatller usage, or use the sis files of the SDK. If it is somebody else's, then do contact the original developer of the application.
Re: component "qt" missing
Or you can install Qt sis file by yourself and see if it works, you need to find right version just by trying different version.
Re: component "qt" missing
Yes can definitely, anyway, if it is somebody else's program, it should be packed for real usage, or it probably should not be used.. or at least used with caution.
