In some cases, after you download the Apprenda installation package the Apprenda Wizard executable used to install the platform will be blocked. This is due to a security mechanism in Windows intended to limit execution of code downloaded from the internet. If you encounter this issue, the Apprenda Wizard will launch, but you may encounter the following error:
That assembly does not allow partially trusted callers.
To correct this issue, right click on the Apprenda.Wizard.exe file and select Properties. Then click on the 'Unblock' button. You can then launch the installer and run through the installation.
