Cannot install version 7.6
I have tried everything to get the latest version of Calibre to install. I get the dreaded "This installation package could not be opened" error. I have turned off all antivirus. I have tried fixes related to the Windows installer. I have tried to install it in safe mode - which does not work because then I get an error that the Windows Installer is not available in safe mode. I have downloaded it from different links.
Can anyone give advice that will actually work? |

2. Check if the Setup File is Blocked Windows sometimes applies blocks to ‘suspicious’ files downloaded. If your setup file is blocked, you’ll see an Unblock option within its properties window. You can unblock a setup file like this: Simultaneously press the Win + X keyboard keys and select File Explorer. Go to the folder you’ve downloaded an affected software setup file to. Right-click the affected software setup file and select Properties. Click the Unblock box on the General tab if you can see one. |
