I have an MSDN subscription and I've installed Visio 2013. I am not able to activate the product and it has reduced to a read-only state.
Any attempts to activate or "Switch Account" are met with "Sorry, we are having some temporary server issues." I've found a few posts referencing removing an office-related key from the registry but this has not helped.
At one point I believe I'd also heard that our network might be blocking activation, but don't have a handle on how that would be coming into play exactly (if at all).
Have others encountered and (hopefully) found a fix to this issue?
Go to Control Panel -> Programs and Features -> Microsoft Visio Professional 2013
Right click on Microsoft Visio Professional 2013 and click on "Change"
Then select "Enter a Product Key" and supply your 25 digit licence key to activate.
