Xcelsius 2008 Licence key not valid

23 Views

I hope someone can help as I am at my wits end with this despite many emails back and forth with support.

I have Xcelsius 4.5 running on Vista. I bought the upgrade to 2008. I installed it but it keeps saying the licence key is invalid. I have been told about the need to change permissions in regedit which I have done but it still will not work.

Update: issue resolved..phew!
