Windows 10 has come under severe flak in the last few days, as discerning users have been unearthing more and more problems with Microsoft's latest desktop operating system, including the latest installation problems with the newest version of iTunes on Windows 10.

Several affected users have been venting their ire about the endless number of issues with Windows 10 on Microsoft support forums and social networking websites such as Reddit, with the intent of finding a permanent solution for all known issues including the iTunes installation bug in Windows 10.

According to Redmond Pie, the iTunes installation bug is leading to persistent errors such as "An error occurred during the installation of assembly Microsoft... HRESULT: 0x80073715", "Apple Mobile Device Service failed to start", and message alerts like "Apple application support was not found (Windows error 2)".

The root cause of the iTunes installation issue has reportedly been attributed to incorrect and incompatible versions of iTunes being downloaded from the Apple's official download page:

Consequently, it is ascertained that the issue can be fixed by manually downloading the latest version of iTunes for Windows 10 via direct Apple server links provided below:

Windows 10 users are advised to download the appropriate iTunes files from the above download links, based on the Windows version (32-bit or 64-bit) installed.

For instance, if you are running a 64-bit Windows configuration, then you need to download iTunes for Windows 64-bit (for older video cards).

Furthermore, it is reported that the 64-bit version of iTunes for older video cards also fixes several other issues such as QuickTime compatibility, playback and interaction with other third-party apps installed on the computer.

Although this version of iTunes may not feature the best user-experience, it is said to be fully functional and confirmed to work without any hassles.
