I cannot install sacred gold. The integrity checker runs and then nothing happens. Task manager shows the installer in processes and nothing continues.
First, try rebooting your computer. Maybe something is running in the background that blocks the installer.
Then, if that doesn't help, de-activate your anti-virus software: sometimes they interfere with non-risky programs as well. After proceeding with the installation, you can re-activate it, of course.
If even that doesn't help, download the installer again.
