Installation problems

Good morning,
I'm tryng to upgrade my actual portable version with 5.22.1, but installer returns this message:

Failed to move ebook-viewer-portable.exe, make sure calibre is not running

Calibre is closed, I tryed also after a reboot and a fresh installation (in a clean folder).

Any suggestions?

Best regards,
Stefano

Could be your Anti Virus software blocking it?

If using Windows, reboot into Safe Mode and try the install again. This will reduce the number of programs running so you can then look for possible candidates if the install fails again.
Or just stop the AV software before running the install and see if that helps

If it is your AV software causing the problem, then you need to find different AV software. No decent AV software will interfere with Calibre.

I suppose a different problem, because I can install the normal version. It is only the portable version to have problems...

Where are you trying to install it to? The directory may be protected. Windows 10 introduced a lot of security features and one blocks writing to what it classes as protected directories especially the Documents folders and similar.

P.S. As a rule you need to provide details such as OS used, where you are installing to and so on. We can only guess what is happening with just a simple error message. The more details explaining what you are doing, where you are doing it and exact error messages all help us to help you.

@stefano664 - you should find ebook-viewer-portable.exe in the folder where you installed portable, try deleting it and then 'reinstall' portable.

Another possibility is the drive you're installing it on is close to full. IIRC the portable install unpacks the calibre-portable-installer-?????.exe to a temporary sub-folder in the install location, it then moves components from there into the destination sub-folders, and then deletes the temporary sub-folder.
