Hi

We bought Visio 2013 Professional (it only came with a key) and downloaded the .img file and created the disc. We are trying to install it on an intranet PC. How do you install it without having a internet connection. During install it keeps popping up windows trying to go online for activation. 

Hi,

Yes, we can activate this VISIO 2013 Pro by using phone. Please skip the activation during installation process first. When the installation is completed, do the following steps:

• Open Visio, click File > Account > Activate Product.

• In the Activation Wizard, click I want to activate the software by telephone > Next.

• Select your country/region.

• Call the Product Activation Center phone number thats under Step 1.
