Having installed Notepad++ with the Windows 10 apps store, it installed by default the 64 bits version. This wasn’t a problem, until I tried to Compare two text files with Notepad++ and Order a list and remove duplicates, which both require a 32 bit version of Notepad++ to work.
The solution is pretty simple – download the 32 bit version from the Notepad++ website, and install it. It will propose by default to update itself the existing installation, without losing any work, like open drafts and files.
On Notepad++ website, download the 32 bit version
During the installation, the program will offer to replace the existing installation, without losing any work
Then, in the old installation folder, which was located in Program Files
Copy the plugins to use with the application in the Program Files (x86) folder
