Install supported from Local Drive Only
  Does anyone have any recommendations as to how I can run checks in a NSIS package to see if the install is run from a local drive. I have an installer that has some issues if it is run from across the network since there is a NIC wrapper that is installed..

Thanks...

Use GetDrives and validate $INSTDIR against it.

For anyone ever looking for how to do this, this is the following piece I used... The benefit of the below code is that I use NSIS as a wrapper for installers and on some the reset the network interface. If the installation is ran from a network source, it breaks the connection back to the source EXE causing a lockup. This forces the user to run the installation from a local source...

Thanks and sorry for the late response Afrow, finally got around to working on this...
