Inexpensive Remote Assistance software? [closed]

Solution 1:

Single Click (UltraVNC)

• Open-Source
• Easy to configure/customize
• Easy to launch (connect to)
• Supports 64-bit clients (according to them at least)

Ultra VNC's 'Single Click' might be what you're looking for. It let's your client (user) launch an executable (no install needed) that opens up a connection (out) to a listening server on your end. It's been pretty flawless for us for connecting to remote users. Here's some info about it: http://lifehacker.com/198532/geek-to-live--tech-support-with-ultravnc-singleclick

Solution 2:

I've used TeamViewer in the past without any issues on Vista clients or 64 bit.
