Notes on upgrading from V2.5 to SpecView Version 3

It is important to note that there are a few changes to terminology since V2.5:

  • Configuration Mode is now known as Edit Mode
  • A Configuration is now known as a Project

V2.5 is also known as SV32, usually  in the C:\SV32 folder, whereas V3 is known as SV3, usually in the C:\SV3 folder.

Ideally, we suggest installing in a folder called SV3. Do not install in the same place as any existing SV32.

Make sure your existing dongle is connected prior to installation. Note: Version 3 will only work with USB and Soft Licenses. It will not work with the older parallel (25-pin) dongles.

The installation program has 3 modes of operation:

  • If SV3 was not installed on the PC previously, then it will install SV3 fully.
  • If this installation is a newer build, then it will update the current installation.
  • If the installation program is re-run for the same build number, then it will offer: Modify/Repair/Remove

It is advisable to reboot the PC after completing the installation process.


RunAsAdminRun either SV3 or SV3_64 as Administrator the first time to allow the system to be setup correctly. Subsequently, it can be run as a non-administrator.

 To do this: Right click the icon and select ‘Run as Administrator’  as shown here:
