Need to figure the INF equiv of %APPDATALOCAL%

[shanselman]

I need to figure the INF equiv of %APPDATALOCAL% because this

HKCR,Directory\Shell\WindowsTerminalHere\command,,,""c:\users\scott\appdata\local\Microsoft\WindowsApps\wt.exe -d " ""%1"""

needs to be something like this

HKCR,Directory\Shell\WindowsTerminalHere\command,,,""PATHTOAPPDATALOCAL\Microsoft\WindowsApps\wt.exe -d " ""%1"""
and so far neither %APPDATALOCAL% nor $APPDATALOCAL$ work

To expand environment variables value must have type REG_EXPAND_SZ. In INF files values are of REG_SZ type by default. To use REG_EXPAND_SZ it is necessary to add 0x00020000 to flags.

Snippet below adds REG_EXPAND_SZ value:

[version]
signature="$CHICAGO$"

[DefaultInstall]
AddReg    = ABC.Reg

[ABC.Reg]
HKCU,test,DisplayName,0x00020000,"%ENV_VARIABLE%"

Not sure what kind of inf file this is, but https://docs.microsoft.com/en-us/windows-hardware/drivers/install/general-syntax-rules-for-inf-files implies that escaping % with % might do the trick?

Also: %APPDATALOCAL% is not valid. I think you mean %LOCALAPPDATA%.

[shanselman]

Yes, thanks! @riverar that's my fat fingers! It's three things

• double escape %%
• REG_EXPAND_SX
• use the correct ENV var ;)
