I tried downloading the self-extracting Windows installer and its telling me that “Some installation files are corrupt. Please download a fresh copy and retry the installation”
When I click ok, WinRAR self-extracting archive tells me
Extracting qt_host_installer.exe
CRC failed in qt_host_installer.exe
I have updated the Windows installer this morning, but it should be OK
I would recommend disabling any anti-virus software temporarily and running the program
