Single Click UltraVNC for remote support Manual

An idiots guide to setting up a remote support using UltraVNC SCI and SCIII

Here is the scenario.

1. You have customers who you want to support
2. You send out software which you want to support
3. You want to be able to upgrade customer software remotely
4. You have an office from which you want to provide the support from, for multiple support personnel

Well, there are many offerings on the market, which cost $150 to $1000's per year.

UltraVNC have two great offerings, known as "Single Click", to solve the above support requirement. It is called Single Click because it allows you to create a small executable package ("Support.exe"), which your customer simply downloads and runs, to give you control if their PC only when they allow you access.

Two versions of Single Click UltraVNC are currently available:
Option 1 : Single Click UltraVNC
Option 2 : Single Click UltraVNC III
