How to assoc*.zip to my dinamic path?

[Adrian Dragne]

Hello, good day,

I found one bug, I cannot associate (with source *.iss), at means, all files with extenstion *.vlax (is zip-renamed) to "{sd}\vlaxcompil\bin\devcinfo.exe".

After I installed my kitt, then Explorer.exe do not start automatically devcinfo.exe, when I click on any file*.vlax.

Root: HKCU; Subkey: "Software\Classes\Applications\Aro10Comp2026\devcinfo26exe\shell\open\command"; ValueType: string; ValueName: ""; ValueData: """{sd}\vlaxcompil\bin\devcinfo.exe"" ""%1"""; Flags: uninsdeletevalue

Hi,

See https://jrsoftware.org/isfaq.php#assoc

First set the [Setup] section directive "ChangesAssociations" to "yes". Then create the 5 [Registry] entries the FAQ shows.

Do note that Windows might choose to not to immediately make your new association the default, because it wants the user to be in control.

Greetings,
Martijn

Also note that you should not hard-code a path like this to your exe.  Use {app} and set your desired parent path as the DefaultDirName so that the user can choose to install it elsewhere if they wish.  It's also considered bad form to default to installing a top-level directory; apps are supposed to default to being installed under {pf}.
