I have been trying to create a virtual app op an application for our lab called GLIMS. It is a progress database application. It has been giving me gray hairs this week!!! If I run the virtual app on any other machine than the one I created it on, I get a message "The application was unable to load a required component: snbd12dm.dll. ..." The virtual app has no reference to the dll it moans about, and the dll is also not installed on the machine I have used to create the virtual app. I have tried this on multiple VMs (XP, 7) and used ZAV 9 & 10 with exactly the same result. My last attempt was on a clean XP machine with no additional software besides ZAV 10 & the required vm tools. HELP!!! This is driving me mad!!
