I happen to have two setups for ImgBurn on my computer, and the size difference is telling:
SetupImgBurn_126.96.36.199.exe 2.06 MB
SetupImgBurn_188.8.131.52.exe 5.83 MB
Sooo, I extracted the contents of both using UniExtract and found the following:
Installer for ImgBurn in the main folder, plus two subfolders, for Plugins and Sounds.
Plugins contains DLLs and images pertaining to ImgBurn only.
Main folder contains three subfolders: Install directory, Plugins directory, and Temp directory
Install directory contains a folder named Uniblue that has three files: DriverScanner, RegistryBooster, and SpeedUpMyPC.
Plugins directory contains ImgBurn DLLs and images plus Ask toolbar .ini and .bmp files
Temp directory contains ApnIC.dll, ApnStub.exe, and Apn Toolbar Installer.exe - all Ask Toolbar related.
So to me it appears that 184.108.40.206 was the last clean version of ImgBurn. I wouldn’t install any version released later than that.
BTW, 220.127.116.11 had no reference to OC within the installer package.
