The software is available in different versions for 32-bits and 64-bits Windows editions. The 32-bits version will work both Windows editions. The 64-bits version will work on 64-bits Windows editions only.
In order to download, you may need to use the "Save Target as..." or "Save to Disk" commands of your Web browser after right-clicking the download link.
The installation files are suitable for new installations only as well as software updates.
If you have previously installed MedCalc, you must close any open (running) copy of MedCalc first. Then execute medcalcsetup.exe and follow the instructions for the installation procedure.
If you want to install the 64-bits version and you have a 32-bits MedCalc version already installed, you should first remove that older MedCalc version through your Windows control panel.
Anti-virus programs can sometimes interfere with the installation process. Temporarily disabling your anti-virus program may help if you're having trouble with your installation. You should re-enable it as soon as installation has been completed.
New: MedCalc file viewer
With the MedCalc file viewer you can open MedCalc files (*.mc1) without the need for a MedCalc license.
