1.6.6 Blink compiles more than a minute

I have downloaded the ZIP version. Copied in ProgramFiles. I have a powerful modern computer. Older versions compile the example Blink for 2-3 seconds.

The new version compiles more than a minute. :frowning:

What could be the problem?

Did you install the previous version? Because extracting the zip into Program Files is bad practice... OR use the installer to install it in Program Files OR donload the ZIP and extract it somewhere in you're storage (Desktop, My documents etc). Program Files is for installers...
