We have received many reports that opening the installer executable of the trial or registered version of ORF fails with the following error message:

“Windows cannot access the specified device, path, or file. You may not have the appropriate permission to access the item.”

This error is shown even if you downloaded and try to run the installer as an Administrator, and you have full control over the file and the folder it resides in.

This is caused by a default Windows security feature (or rather: annoyance) to prevent EXE files from running before you Unblock them (huh?)

To fix this, do the following:

1. Right-click the file in Windows Explorer, select Properties
2. On the General tab, click the Unblock button

Now you can proceed with the installation.
