Hi everybody,
I have the same trouble as you all : Your product license has reached the activation limit. Contact the Parallels support team for assistance.
I have two computers. Both have just been clean installed with El Capitan. I have 2 Parallels Licences : the first one for my Macbook Air, and a second one for an iMac. The first licence is a Business Edition, and it runs perfectly on the MBA. The second one was running on Yosemite before installation. But I can't reinstall it on the iMac (under El Capitan) with the same "error message".
In the Parallels Web Site, in my account, only one key appears in the list ! (and all my old keys : I use Parallels since the 5.0 version), but my second key (for the Business Edition) doesn't ! Both of them are registered on the same email address, I have my proof of purchase for both of them.
I can't use my iMac with Parallels anymore, and I must change my laptop soon, so what is the solution to reinstall without loosing to much time ?
Many thanks in advance
(Sorry for my poor english)
