Why Does an "Input String" Error Occur During Envision Installation?

Symptoms

When installing Envision on a Windows 7 or Windows Server 2008 machine, the following error occurs: "Input String was not in a correct format."

Cause

UAC is not disabled during installation.

Resolution

Disable UAC, and then restart the machine. Once installation is complete, you can turn UAC on again.

Cause

Envision bit version (32-bit/64-bit) is not the same as the bit version of Visio installed.

Resolution

The Envision bit version should match the Visio bit version installed in that machine. If 32-bit Visio is installed in a 64-bit Windows 7 machine, 32-bit Envision must be installed.
