  • I searched existing issues and did not find a duplicate.
  • I am describing a concrete problem or use case, not just a vague idea.

Area

Build, CI, or release tooling

Problem or use case

Managed corporate Windows machines commonly exclude a dedicated volume from real-time scanning so dev tooling is usable, and scan the system volume aggressively. Given the file count in #5876 — 14,687 files written at install, each a separate open/stat/scan on a cold start — the install location matters for startup cost on these machines.

T3 Code cannot target that volume. createBuildConfig in scripts/build-desktop-artifact.ts sets no nsis block, so electron-builder applies oneClick: true and allowToChangeInstallationDirectory: false, fixing the install to %LOCALAPPDATA%\Programs\....

Proposed solution

apps/desktop/resources/installer.nsh — auto-detected via getResource(this.options.include, "installer.nsh") in NsisTarget.ts, so no change to build-desktop-artifact.ts and no new config key:

!macro preInit
 ReadEnvStr$0"T3CODE_INSTALL_DIR"${if}$0!="" SetRegView64 WriteRegExpandStrHKCU"${INSTALL_REGISTRY_KEY}" InstallLocation "$0" SetRegView32 WriteRegExpandStrHKCU"${INSTALL_REGISTRY_KEY}" InstallLocation "$0"${endif}!macroend

preInit runs at the top of .onInit, before multiUser.nsh reads InstallLocation to pick $INSTDIR. Unset variable means today's behavior, unchanged.

Why this matters

Unblocks installs on machines where the system volume is scanned and a dev volume is not.

Smallest useful scope

The macro above, HKCU only. No installer UI, no nsis config block.

Alternatives considered

  • Pre-seeding InstallLocation manually. Works per electron-builder's docs, but requires computing UUIDv5(appId, 50e065bc-3134-11e6-9bab-38c9862bdaf3) and a manual registry edit — not something to ask of users on a managed machine.
  • oneClick: false + allowToChangeInstallationDirectory: true. Adds installer pages for every user.
  • A junction from %LOCALAPPDATA%. Exclusions match the accessed path, so the I/O is still scanned.

Risks or tradeoffs

Takes effect on install only, not on an existing one. Per-user path only; an elevated per-machine installer would not inherit the user environment. Needs a line in the Windows install docs to be discoverable.

                      •  I searched existing issues and did not find a duplicate.
                      •  I am describing a concrete problem or use case, not just a vague idea.
                      Area
                      Build, CI, or release tooling
                      Problem or use case
                      Managed corporate Windows machines commonly exclude a dedicated volume from real-time scanning so dev tooling is usable, and scan the system volume aggressively. Given the file count in #5876 — 14,687 files written at install, each a separate open/stat/scan on a cold start — the install location matters for startup cost on these machines.
                      T3 Code cannot target that volume. createBuildConfig in scripts/build-desktop-artifact.ts sets no nsis block, so electron-builder applies oneClick: true and allowToChangeInstallationDirectory: false, fixing the install to %LOCALAPPDATA%\Programs\....
                      Proposed solution
                      apps/desktop/resources/installer.nsh — auto-detected via getResource(this.options.include, "installer.nsh") in NsisTarget.ts, so no change to build-desktop-artifact.ts and no new config key:
                      !macro preInit
 ReadEnvStr$0"T3CODE_INSTALL_DIR"${if}$0!="" SetRegView64 WriteRegExpandStrHKCU"${INSTALL_REGISTRY_KEY}" InstallLocation "$0" SetRegView32 WriteRegExpandStrHKCU"${INSTALL_REGISTRY_KEY}" InstallLocation "$0"${endif}!macroend
                      preInit runs at the top of .onInit, before multiUser.nsh reads InstallLocation to pick $INSTDIR. Unset variable means today's behavior, unchanged.
                      Why this matters
                      Unblocks installs on machines where the system volume is scanned and a dev volume is not.
                      Smallest useful scope
                      The macro above, HKCU only. No installer UI, no nsis config block.
                      Alternatives considered
                      • Pre-seeding InstallLocation manually. Works per electron-builder's docs, but requires computing UUIDv5(appId, 50e065bc-3134-11e6-9bab-38c9862bdaf3) and a manual registry edit — not something to ask of users on a managed machine.
                      • oneClick: false + allowToChangeInstallationDirectory: true. Adds installer pages for every user.
                      • A junction from %LOCALAPPDATA%. Exclusions match the accessed path, so the I/O is still scanned.
                      Risks or tradeoffs
                      Takes effect on install only, not on an existing one. Per-user path only; an elevated per-machine installer would not inherit the user environment. Needs a line in the Windows install docs to be discoverable.
