Keep running batch loop after starting .exe - loops

Question

My program.exe sometimes stops. I have made batch script that checks if program is running and start it if not in loop.
The problem is loop is exiting after program.exe is started and runned.
I need to keep running the loop to keep checking every 5 mins if program still running or needs to be started again.
set loopcount=10000
:loop
tasklist /FI "IMAGENAME eq program.exe" /FO CSV > search.log
FINDSTR program.exe search.log > found.log
FOR /F %%A IN (found.log) DO IF %%~zA EQU 0 GOTO end
echo Starting..
start /b C:\_Program\program.exe
:end
del search.log
del found.log
echo Waiting..
timeout /t 300 /nobreak
if %loopcount%==0 goto exitloop
goto loop
:exitloop
pause

Answer 1

Batch File
If you have to use a batch file, I'd suggest:
Removing the loop
Running it every 5 minutes using a scheduled task
A scheduled task is more robust than an infinite loop in case the process crashes.
Run this once to schedule a task that repeats every 5 minutes:
schtasks /CREATE /SC DAILY /MO 1 /TN 'Name To Give the Scheduled Task' /TR 'C:\path\to\your\script.bat' /ST 0:00 /RI 5 /DU 24:00
PowerShell
If you can use PowerShell, the equivalent is a bit simpler:
if ($null -eq (ps program -ErrorAction SilentlyContinue)) {
saps C:\_Program\program.exe
}
Run this once to schedule a task that repeats every 5 minutes:
schtasks /CREATE /SC DAILY /MO 1 /TN 'Name To Give the Scheduled Task' /TR 'powershell -EB C:\path\to\your\script.ps1' /ST 0:00 /RI 5 /DU 24:00

Answer 2

It might be as simple as:
#echo off
:repeat
tasklist | findstr /i "program.exe">nul
if not %errorlevel% equ 0 start /b "C:\_Program\program.exe"
timeout /t 10 /nobreak>nul && goto :repeat
This does tasklist and we use findstr to determine errorlevel if not 0 start program, timeout for 10 seconds and repeat, no external files needed.

Answer 3

Here is an example to test.
To achieve continuously check (in loop) the existence of process "WinRAR.exe" (as an example of application to check); so you can change of course the path and the process name to check.
#echo off
Set "MyApplication=%Programfiles%\WinRAR\WinRAR.exe"
Set "MyProcess=WinRAR.exe"
Color 9B
Title Check Running process "%MyProcess%"
mode con cols=75 lines=2
:Loop
cls
tasklist /nh /fi "imagename eq %MyProcess%" 2>nul |find /i "%MyProcess%" >nul
If not errorlevel 1 (Echo "%MyProcess%" is running) else (start "" "%MyApplication%")
ping -n 60 127.0.0.1 >nul
goto Loop
