I installed a MS Visual Basic 2005 Express a month ago. I didn't register this product, so my copy expired. Now, I install MS Visual C# 2005 Express. Setup says that my version of MS Visual C# expired. I want to register this product, but it's not go. Could you give me some advice

C# Express expired

Have you uninstalled all of the VS Products... Restarted the machine and tryed it again..

First up... why didn’t you register it during the first month
Before attempting to install it again, did you uninstall the previous install
It’s as easy as choosing Register Product from the Help menu and then following the prompts, waiting a short time for an email and plugging in the key you receive.
