support@imgburn - Lightning i've contacted you by email please read. in ImgBurn Bugs Posted January 6, 2014 · Edited January 7, 2014 by GraphiX2004 I've deleted my post after 15 re-installs and everything upto the 15th re-install and test of this problem, on the 16th install the microsoft installer issue popped up right before installing imgburn, so it's not imgburn causing the issue even through 15 installs and tests said otherwise. Lightning has tested his app out by doing exactly what i've done and found no error so sorry guys, and girls. but after 15 re-installs and testing this issue and it happening every single time without fail, you can't say at all it was a rushed post or some kinda of hoax. i've been using nero, samsung link, camtasia Studio, Acronis and hard drive sent for what 8 years now? and never seen this problem when running the .msi installers. There's also a microsoft forum with people with this same bizare error no body knows how it happens or why, even microsoft tech can't answer either. do a google search for Microsoft Installer v5.01 you'll see what i mean. Anyway sorry lightning after all the testing i did when i found this installer error i thought i'd contact you directly just incase. anyway cheers laters.
