For the last couple of days, I have encountered a weird error while opening iTunes 184.108.40.206: This copy of iTunes is corrupted or is not installed correctly. Please reinstall iTunes. (-42037). Normally, I never experienced any other error in iTunes, but this was something really strange.
I didn’t know what to do with this error; but all of a sudden, I recollected that I could get some help from control panel of my Windows PC (this error occurs in Windows PC more often). So I opened the control panel and followed a few simple steps, and whoa! It worked…
