License key check failed. Rational Software Development Platform

I ran into an annoying error today, one that doesn’t show its face very often and you will probably see it once or twice in a lifetime if working in an environment that uses Rational Software Development and also if you provide support for a team or company that is using it. The error “The License key check failed” will appear after a while or in some cases even suddenly after the activation and mostly (but not always) after performing an activation process that will result in installing a permanent activation key. Depending on what version you are using...

Cannot detect USB flash drive or an external hard disk drive

I won’t guarantee this applies to each and every similar situation and as you will notice, it might not work for some of you.

Make COM Ports available for software that reads them as protected

When you connect devices to a computer using COM physical ports or USB ports (depending on the device connected) they get a COM port number assigned that you can see in your device manager, under “Ports” section. The thing you should keep in mind is that under this section you can only see the ports that are currently in use. I won’t get into more details than needed like the devices that you can connect because this is not the purpose of this article. This and many more things regarding COM/USB/LPT ports will be covered in a future article...
