I have two PCs: Windows 7 and Windows 8.1, both with QT 5.5.1 installed.
On windows 7 TopazStudio 1.11.7 was successfully installed and launched 1st time (from last screen of installer), but only two menus (Adjustments and Help) were available.
I have closed app and next run it has shown a message "Application cannot be launched correctly (0xc000007b). Click OK to close application". Reboots, uninstalls/reinstalls have not helped.
On windows 8.1 I cannot even launch Installer - it appears for 1-2 sec in tasks list (Task Manager) with no window on screen and closes.
Is it because of QT installed or this is independent problem?
Perhaps need to clean/remove something in addition to uninstall on Win7 PC before reinstalling?
