Unknown module(s) in Qt: opcua

[TheCipo76]

Hello,
i purchased Qt OPC UA and installed it from Maintenance Tool (Qt Automation) but when in an empty project add:

QT += opcua

in .pro file i have this issue:

Project ERROR: Unknown module(s) in QT: opcua

If i use Qt 5.15.2 no problem was founded but with other version of Qt (Qt 5.12 or Qt 6.04) i got the issue

In the Maintenance Tool i can install Qt Automation opc ua only for Qt 5.15.2

Someone can help me?
Thanks in advance.

hi
You have multiple qt installations but only your Qt 5.15.2 has the opcua plugin installed i guess.

@ODБOï Yes, this is the problem.. why i can't use it with Qt 6.0.4??

Because you have not installed opcua for Qt 6.04 ;)

If you want to use it with Qt 6.0.4 you need a build for Qt 6.0.4, you cannot mix Qt version

you added this later :p , in that case i can't tell. I never installed it using the Maintenance Tool, iusually build it manually, and you have o build it for every qt version you want to use
