One of the first things I installed on my new system was ImgBurn 2.5.7.0. There's no records in my firewall logs of any OpenCandy stuff, nor are there any policies set in regards to the program, SweetLabs Inc., or anything related. Based on that, and forum posts on the ImgBurn website, I think 2.5.7.0 is the best you can do without getting hit with OpenCandy stuff.
After reading some posts about OpenCandy I think a lot of people are failing to properly express why OpenCandy is bad. Downloading stuff in order to present offers to users while running with administrative rights through an installer isn't the big danger, it's that if an offer is malformed, intentionally or not, it could install stuff without the user's consent, which adds an extra hassle to remove, especially if it's malicious stuff. This may be against OpenCandy's policies and they may remove such things from their network when they're informed, but the simple fact is that the danger is present, people are affected by these incidents, and thus people would rather not take the risk.
Considering how rapidly the author of ImgBurn is taking flak for this decision I have a hunch we may be seeing a 2.5.8.1 in the near future that has OpenCandy taken out. ;)
