Apple application support was not found

Hallelujah! Worked perfectly. Thanks.

I used 7zip portable instead, but I was able to open the inside of the iTunes6464setup.exe. I realized I somehow installed AppleApplicationSupport.msi (32-bit) previously. When I ran that MSI, I was given an option to Repair/Remove. I removed successfully. I also installed the 64-bit version and the re-installed it. Both went successfully. I think there's some wonkiness going on with 32-bit vs 64-bit. Depending on what you had installed in previous versions of iTunes, there may be conflicts when you upgrade to newer versions... or uninstall iTunes but still have lingering files that are conflict with what seems like a "fresh" install.

I did your instructions step by step and this is the message that I got:

b noir hasn't dropped by lately, perhaps I can help.

For general advice see Troubleshooting issues with iTunes for Windows updates.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try theiTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.

The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if Apple Application Support won't install normally.

Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

This solution did the trick. Thank you.

Maybe your OS is too old and you can try installing an older version of iTunes? Use 7zip to open iTunes setup exe and just install apple application support only.

Try old versions com
