1.10. How do I download the software if I get a message about the signature being corrupt or invalid?
The CLC software installers are signed with a valid signature.
It should be possible to open the properties of the installer on your new computer and check. How to do this on a Windows 7 system is shown below.
November 2013: A recent Microsoft security update causes IE to (wrongly) report that the signature on our installers is corrupt or invalid. This issue exists for other software as well as CLC software. If you are encountering this issue and cannot download the installer file for CLC software, please try using another web browser. You can then check the signature on the downloaded installer, should you wish.
