Else statement skips and Test-Path does not match up

cvn65-weaps · 2019-09-13T19:12:54.000Z

I have one application to replace another application. The install seems to work fine (mostly). The problem is the uninstall of the 2nd application. There are (at least) 4 different versions that require 4 separate uninstall commands in order to run.

So, please see the below code with comments:

#Section 4
$AppService = “C:\Program Files\Application\ApplicationService.exe”
$AppServiceExists = Test-Path $AppService

If ($AppServiceExists -eq $True) {Add-Content \FileShare\ApplicationLogs$COMPUTERNAME.log “Application Exists”
}else
{
Add-Content \FileShare\ApplicationLogs$COMPUTERNAME.log “Application Does not exist”
cmd.exe /c \FileShare\Application\Application.exe /install /quiet /norestart
}

If ($AppServiceExists -eq $True) {Add-Content \FileShare\ApplicationLogs$COMPUTERNAME.log “Application Installed”
}Else
{
Add-Content \FileShare\ApplicationLogs$COMPUTERNAME.log “Check install of Application” #This was logged. A - I need to retest with Test-Path… Easy enough.
Exit-PSSession #B - The session should have exited here (since I did not retest with Test-Path). Instead, it continued on to Section 5. This is a problem as I need it to stop here if there is an error.
}

CVN65-WEAPS:

There are (at least) 4 different versions that require 4 separate uninstall commands in order to run.

i’d look into a switch statement

$version = # code to get version

switch($version){
    '1.2'{ <#Code to remove version 1.2#>}
    '1.4'{ <#Code to remove version 1.4#>}
    '1.5'{ <#Code to remove version 1.5#>}
    default { <# code if none of the versions match#>}
}

Thanks. I’ll give that a shot. I attempted to post the code. Missed the “Language” part (Defaulted to English, so I didn’t check it.)

cvn65-weaps · 2019-09-13T20:00:24.000Z

This mostly worked:

Symantec EndPoint Protection is not installed
Symantec EndPoint Protection is not installed
Symantec EndPoint Protection is not installed
Symantec EndPoint Protection is not installed
SEP v14.0.2415.0200 uninstalled
Symantec EndPoint Protection is not installed

(The code insert still isn’t working for me…)

have you tried a different browser?

That looks much cleaner, does that work now?

cvn65-weaps · 2019-09-13T21:48:43.000Z

No. That was a copy/paste directly.

Did you try to invoke the cmd command?

I may have mis-read this. Yes, this portion now works.

The only portion not working is the Exit-PSSession. I just changed it to (simply) Exit and it now appears to work properly.

Thanks all!
