Improper installation location for 64-bit version on Windows?

[mikunimaru]

Description
Even though I installed Mozc with the 64-bit installer, Mozc is placed in the installation location for 32-bit.

Steps to reproduce
Steps to reproduce the behavior:

1. Click on Mozc64.msi to install Mozc.

Expected behavior
Mozc will be installed under 'Program Files'.

Actual behavior
Mozc will be installed under 'Program Files (x86)'.

Version or commit-id
Mozc-2.28.5080.100+24.11.oss

Environment

• OS:Windows

Thank you for your suggestion.

This is actually a known issue inherited from Google Japanese Input, and for now we'd like to keep the current configuration to minimize the diff between Google Japanese Input and OSS Mozc.

The thing is that the following executables are still 32-bit even if you install Mozc64.msi.

• mozc_tool.exe
• mozc_ja_tip32.dll
• msvcp140.dll
• vcruntime140.dll
• Qt5Core.dll
• Qt5Gui.dll
• Qt5Widgets.dll
• platforms/qwindows.dll

So for those binaries, the location %ProgramFiles(x86)%/Mozc is indeed consistent.

I know it looks a bit strange, but given that there is no user visible impact I'd like to keep the current installation location until Google Japanese Input also starts using new installation location, which may require careful migration strategy for existing users.
