Im running windows 7 64 bit and cannot install.
Error says Installer integrity check has failed. Common causes include incomplete download and damaged media.
I tried to reinstall but same error
It sounds like your installer may have been corrupted during download. Try downloading the installer again.
This is how you solve this Problem:
Windows >> RUN >> cmd
Drag your .exe file into the CMD window, leave space, write /NCRC and press enter.
The installer should open now corectly.
same issue on my windows 7 64bit machine. no amount of re-downloading helps. the /NCRC workaround is fine until the installer dies halfway through installation
