Environment Variable in MSIX Using PSF
In your example the executable is not defined correctly and the slashes are not escaped in the variable value. Here is an example that should work, but remember to add EnvVarFixup64.dll as TIMOTHY_MANGAN mentioned, but keep the json the same - "dll": "EnvVarFixup.dll"
{
"applications": [
{
"id": "SevenZFM",
"executable": "VFS\\ProgramFilesX64\\7-Zip\\7zFM.exe",
"arguments": "",
"workingDirectory": ""
}
],
"processes": [
{
"executable": ".*",
"fixups": [
{
"dll": "EnvVarFixup.dll",
"config": {
"envVars": [
{
"name": "Z",
"useregistry": "false",
"value": "C:\\temp"
}
]
}
}
]
}
]
}
Thank you for your response!
As you suggested I changed my config json accordingly, but I can't find the variable.
See the below json file.
Abhi211 How are you checking for the variable? You will not see it in process explorer or CMD. The only way I was able to actually verify that the fixup works was by writing my own C# console program that displays the value of the environment variable.
I am using Invoke-CommandInDesktopPackage -PackageFamilyName "7Zip_8h66172c634n0" -command "cmd.exe" -AppId "SevenZFM" -PreventBreakaway to check the variable inside the bubble. Using the SET command in the cmd inside the bubble.
Will this not work?
No, it may be the app is fine and your test is leading you astray!
The Invoke-CommandInDesktopPackage, in general, is OK to get into the environment, but as you are not starting a PsfLauncher, the PSF is not injected into your cmd process, so the fixup is unavailable to your test..
The best thing I would recommend to troubleshoot is to add the Debug version of the PSF, and run the application (causing it to read the value of the environment variable), and using the SysInternals tool DebugView to capture debug output. Of interest in the output is the launch of the primary app by PsfLauncher (checking that the fixup dll is successfully loaded into the process and that it doesn't complain about a bad config.json file), and then when GetEnvironmentVariable is called by the app.
