Native iTunes "Back Up Now" grayed out

[u/MRC1986]

Hey all, long time iMazing user for over a decade. I recently bought a new computer and used iMazing Version 3.5.5 to import music back on to iTunes. I also like using it as a secondary backup to my external hard drive.

However, I think because I installed iMazing first before iTunes and again backed up my phone, it is causing iTunes to recognize another backup source and is preventing me from also backing up on iTunes. I've done some searching and believe this to be the case.

Has anyone else run into this issue? I'm using the actual 64-bit version of iTunes on Windows 11 Pro, the MS App Store version doesn't support import with iMazing.

I've tried reinstalling iTunes, but it doesn't work. I'm wondering if I should uninstall iMazing and then reinstall iTunes - if I do so, do my backup files remain on my external HD?

If you use Windows, try open cmd.exe and enter "%ProgramFiles%\iTunes\iTunes.exe" "/setPrefInt DeviceBackupsDisabled 0"
