The link below will download the setup file for Version 3.  The changes and new features in this release are detailed in the release notes here.    If you are installing on Windows XP, please see here first.

This Setup file will perform a fresh installation of V3 or will update an older installation.
We suggest installing in a folder called SV3.  Do not install in the same place as any existing Version 2.5 (SV32)

Important note before you download!

If you are upgrading your V3 installation (that includes updating from a lower build to a higher build), or are moving from V2.5 to V3, then you MUST check the Update Subscription status first.  This can be found from the Menus:
Help->Registration Info.              

In V2.5, the Update Subscription was called ‘Free Updates’.

If the Update Subscription has expired, then you will not be able to install the software. Please contact your SpecView representative or SpecView directly to discuss Update Subscriptions.  More help on SpecView Licensing is here.

If you are upgrading from V2.5 to V3, then also check that the ‘Version 3’ option is enabled in the License. This is also shown in the screenshot on the right.

Note: SpecView will run in DEMO mode for 10 minutes if a license is not installed.
