IFW - Windows Registry

Hi,

Does anyone know how to read/store a value from a Windows Registry key? And if a key has more than one value, how to read a concrete value?

Right now am able to add keys and values to the registry as remove them when uninstalling the application, but can´t store a value. I have been searching for examples without any success. Any help would be welcome.

Thanks in advance.

Hi,

there is an example on our wiki: https://wiki.qt.io/Assigning_a_file_type_to_an_Application_on_Windows#How_to_do_it. Search for the function SetHkcrUserRegKey.

Hope this helps!

Many thanks @Wieland,

but my problem is with the installer script (sorry for not having explained before (-_-)). The application is fine according to the customer feedback.

Am trying to check the existence of previous installations and if so, check which version is installed. For this, I have created a registry entry containing the application path and installed version, but I don´t know how to compare the current installation version with the previously installed one.

Thanks in advance.
