I have searched google, and I have also tried to search the forums/tutorials here, but to no avail. When I start the .exe file for C&A to install it, there is a command prompt and a popup window saying that there was an illegal instruction. The window gives me an option to ignore or to cancel. Is this normal? or could I have gotten a faulty version? I just want to make sure that what I'm bringing onto my computer doesn't destroy it.
