STEAM EDITION SUPPORT
This version adds support for FSX Steam Edition (FSX:SE). Note that it will not install to FSX:SE if there is a Microsoft FSX (MS-FSX) installation on the system. (VRS does not yet recommend migration to FSX:SE for those that have working copies of MS-FSX) FSX:SE is only supported if it is the only version of FSX installed on the system. (NOTE: P3D is effectively independent, so its presence or absence on a system has no effect on the VRS FSX installer behavior)

1.4.2.0 only supports the current FSX:SE version. (10.0.62608.0) 1.4.2.0 will not work on any future FSX:SE updates pushed out by Dovetail. Unfortunately, there's no way around this, and no way to prevent FSX:SE updates. VRS will work to quickly release updated installers when new versions of FSX:SE are pushed out, but it may take a few days.

ACM/TPM Name Changes
The executable names for the ACM and TPM have changed. This means that if you've manually created shortcuts for them (perhaps by pinning them to your taskbar or start menu) the old shortcuts will no longer work. You'll need to remove the old shortcuts, then re-pin the new shortcuts.

IMPORTANT NOTES:
You MUST first install the TacPack and only then can you install the Superbug
Installation will blow away anything in the Aircraft folder, including, but not limited to:
Custom liveries: Export your custom liveries BEFORE installing, and re-import (via ACM) afterwards
All preferences: If you have a multi-axis throttle , you will need to reselect that option via the
ACM-->Preferences-->Controllers
Custom MU files: Save any custom MU files in a safe location before installing.
