Yes, eVSM essentially creates Visio files. These can be viewed in Visio without eVSM. However to edit the file, you need eVSM. You can also save your maps in PDF format which can be viewed even without Visio.

You may encounter this issue if Visio is not installed on your machine or if Visio is not set as the default program for .vstx files.

If Visio is installed and you're still experiencing the issue, follow these steps to associate Visio with .vstx files:

The eVSM software is an add-on for Microsoft Visio and runs anywhere the desktop version of Visio is supported.

It can also run on a Mac, provided Windows is installed via Bootcamp or Parallels. Currently, Visio—and by extension eVSM—is not supported on iPads or smartphones. However, eVSM is fully supported on Windows tablet PCs, including the Microsoft Surface Pro.

Note also that eVSM is required to create and edit eVSM maps. These maps can be exported to PDF format, which can then be viewed on any device or platform.

Yes, eVSM v10 (and later versions) is 64 bit compatible for Windows, Visio, and Excel. Microsoft Excel and Visio must BOTH be either the 32 bit version or the 64 bit version. Full 64-bit configuration is recommended for best performance.

The two main considerations for eVSM performance tend to be CPU clock speed and RAM available. We recommend using a machine with at least 16GB of RAM available at a minimum. Having 32-64GB should provide better performance with eVSM, as long as you are running the 64 bit editions of Microsoft Visio and Excel. A machine running dual core processors with around 2GHz per core should perform sufficiently.
