I am struggling to get this powershell replace (command in a batch) text to work;

@echo off
pushd %~dp0
setlocal EnableDelayedExpansion

::enable PS commands in batch
set "Ps_Bypass=PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command"

set /p install=Add File1..(y)es (n)o:
if "%install%"=="n" %Ps_Bypass% "(gc "files.txt") -replace '%FILE1%="Install File One.zip"', ''" ^| Set-Content files.txt

If the user presses no, the entry %FILE1%=”Install File One.zip” needs to be blanked from the files.txt, otherwise left leaving a list of chosen files for another program.

There are a few other lines the same just different file names.

I can get the command to blank any other words or strings (without unusual chars) in the files.txt so I know it will work but there is something in the string content causing a problem. There are no errors, it just doest blank the entry.

I have tried adding back ticks, back slashes, carrots in front of the %’s + = and also double quoting. The closest I got was to the Install File One.zip text being deleted but the %file1%= remained!

Been using this technique to replace text for a while in various things but this string with %+=+”” is giving me a headache!!

Any help, great appreaciated – thanks…
