When installing VMware View Composer, I was receiving the following error:
"Application Error, The exception unknown software exception (0x0000409) Occurred"
Turns out this was an issue with installation privileges. Rather than installing the software as a domain administrator, I simply logged into the local Administrator account on the machine and installed it.
Alternatively, just right-clicking the installer and selecting "Run as Administrator" works as well.
Thanks for the heads up
