Hi,
I just updated to the latest version. The installation appears to have worked, and I'm able to run this great program, but during installation I got the following error message: Staging Sparse Package failed
(details in attached jpeg).
Windows cannot install package
35795FlorianHeidenreich,.Mp3tag.ShellExtension\_3.16.1.0\_x64\_hyhc9 4k68ebpm because it is already installed with a different external location.
How can I correct this?
Many thanks for your help - and for this wonderful software!

Could it be that you installed a 64-bit version over an existing 32-bit version?

> I've released a [64-bit version of Mp3tag](https://community.mp3tag.de/t/455) a few days ago and received a few questions about differences between the 32-bit version and the 64-bit version. To make it short, there should not be any noticeable differences except for two things: The 64-bit version uses 64-bits to address memory and is no longer limited to 2 GB per application. While the [Library](https://docs.mp3tag.de/customization/options/library) feature of Mp3tag is already a very viable solution for large libraries, loosening the memory restriction is one of the key benefits of …

ohrenkino, thank you so much!
That was an amazingly quick and helpful reply.
It didn't occur to me to uninstall, sorry!
After the problem initially occurred, I tried installing the 64bit program in Program Files (x86).
Now I've uninstalled the program, deleted the MP3 program directory in the above directory and in Program Files, then reinstalled the program. (I'd backed up configuration, but that turned out to be unneccessary.)
Anyway, installation went fine.
Thanks again - wishing you the best and hoping the universe is equally helpful to you.
