Chocolatey Preinstaller Checks Extension 0.0.2

##Chocolatey Preinstaller Checks Extension is a Chocolatey extension that intercepts and runs checks before installing or uninstalling a program. This extension will start working automatically once installed and does NOT need to be implemented by package creators/maintainers. Chocolatey Preinstaller Checks Extension is meant to be installed and used directly by Chocolatey end users.

###PURPOSE:

This extension attempts to head off problems related to:

• https://github.com/chocolatey/choco/issues/544
• https://github.com/chocolatey/choco/issues/619
• https://github.com/chocolatey/choco/issues/761
• https://github.com/chocolatey/choco/issues/780
• https://github.com/chocolatey/choco/issues/1526
• https://github.com/chocolatey/choco/issues/1548
• https://github.com/chocolatey/choco/issues/1579
• and possibly others until such time that Chocolatey natively handles these issues better and this extension becomes moot. (Rumored to be 1.0.0 milestone)

Chocolatey Preinstaller Checks Extension's main purpose is to fend off specific types of problems before they occur. Currently Chocolatey (choco.exe) is not multi-instance friendly. If you try to install or uninstall packages using choco.exe in two Command Prompts at the same time, strange (bad!) things may occur. Chocolatey Preinstaller Checks Extension can avoid these strange (bad!) things by intercepting calls to install and uninstall programs and warn about the situation, wait for previous instances to finish, or abort; totally configurable. Chocolatey Preinstaller Checks Extension also checks Windows Installer to see if it's busy and will warn, make MSI installer and uninstaller programs wait until Windows Installer has finished processing the other program, or abort. Chocolatey Preinstaller Checks Extension only runs before PROGRAM installations and uninstallations. It does not perform any functions related to portable packages or other choco commands.

###FEATURES:

• Chocolatey Preinstaller Checks Extension is completely configurable to warn, wait, or abort.
• Chocolatey Preinstaller Checks Extension will check if there is a pending reboot and warn you about it if so.
• Chocolatey Preinstaller Checks Extension will check if Windows Installer is already running and warn, wait for it to finish, or abort.
• Chocolatey Preinstaller Checks Extension will check if there are instances of choco.exe already running and warn, wait for it to finish, or abort.
