Does eVSM run in SharePoint?

It does, but we do not recommend editing or solving an eVSM map directly on Sharepoint. Two reasons for this:

1. eVSM needs to create additional files in the folder the Visio file is in. If you have restrictions in your login you will run into problems.
2. Performance will suffer because for some operations you will be slowed down by network bandwidth and traffic (for communication between your CPU and the SharePoint server).

Best way to work with SharePoint is check the file(s) out for local processing and upload when you are done.
