Update: As pesos kindly pointed out, Apple has released a fixed version of QuickTime 7.7.8 that installs on Windows 10 and lower. Get it here: https://support.apple.com/kb/DL837?viewlocale=en_US&locale=en_US -----------* * * * ----------------- After releasing the latest security/bugfix of QuickTime 7 on Windows, it's now Vista and Win7 only, plainly refuses to install on Windows 8 or Windows 10. http://ipb.s3.amazonaws.com/uploads...humb.png.6d35f6005cc7469d9575fc2ea4aae4c5.png It also states this on the QuickTime download page, as if its the year 2007, no mention of newer Windows versions. The update is certainly an important one for those few of us who use QuickTime on Windows, as a security and memory leak patch. There are ways to install it through major hoopjumping, but I'd rather not risk it. I'm not that tech-savvy. Reading the instructions made me go crosseyed. What happened? Why no explanation? Why Vista and Win7, if it runs on those it probably runs on Win8 and Win10 as well - and in fact it does run fine on those versions of Windows according to those who managed to force-install it.
