It got harder to install Office 2010

I've moved around a 3 computer license for Office 2010 Home many many times. I know the routine. I have to put in the product code, but then it tells me I have it on too many computers, so I have to click the radio button for making a phone call.

But today when I went through the routine, the message said that phone calls were no longer available. I was stuck.

So I googled the exact message it threw, and lo and behold, I found a search hit with the phone number. I called that number, and that triggered a similar process as the old kind (many sets of six numbers) but it required me to do it by phone, rather than web.

It worked.

For U.S.A., the phone number was 866-421-7141
