Dino Crisis 1:
When I try to start the game I get the message "Additional main memory needed. Please close all other applications. It might be nessecary to reboot the computer."

I am on

Win 11,
64GB RAM (25% used)
Ryzen 9 7900X
RTX 4080s
SSD 700GB free.

System is up to date and rebooted.

P.S.: Playing around with dX settings didn't help.

Problem was solved further down by Midoryu. The Riva Tuner Statistics Server is the problem. :)

Same for me with first game.

Same here!

I sent support message, if they get back to me with anything I'll let you guys know.

Had the same issue - first game does not like RTSS/Riva Tuner Statistics Server (is included in MSI Afterburner)

Setting RTSS to ignore the DINO.EXE did not help - I need to close RTSS.exe before launching the game.

Wrote a short .bat script for that which, when run as admin, closes RTSS.exe and launches the game - it waits a few sconds for the game to have launched, before it launches RTSS again.

UPDATE - Edited text and script to reflect this:
RTSS only appears to prevent the launch, but once the game is running, it works fine even with it on.
So after game launch, app can be started again to be able to take screenshots in-game. So no need for me to set up Greenshot as an alternative which I had just completed...


HOW TO USE THE BAT SCRIPT
Put the following in a text file, rename the file from .txt to .bat and launch as admin via right-click or ctrl+shift+enter :

prompt $
@echo off
cls
echo Requires admin privileges, as RTSS runs in admin mode.
echo Ending RTSS to launch DINO.EXE
echo.
taskkill /f /im RTSS.exe 2>1>nul
timeout /t 2
start "" "D:\GOG Games\Dino Crisis\DINO.exe"
timeout /t 5
echo.
echo Relaunching RTSS...
start "" "D:\Program Files (x86)\RivaTuner Statistics Server\RTSS.exe"
timeout /t 8
exit

Edited immediately after: Fixed typos.
Edit 2 a bit later: Added instructions how to use batch files, just in case.
Edit 3 6 hours later: Edited text to relfect that RTSS only prevents the launch of the game, but can be used without issue once the game is running already. Attached screenshot to show it works fine.

I also experienced this issue and sent a support ticket, and yet to hear back.

Can confirm that after closing MSI Afterburner and Rivatuner I was able to launch the game.

Hey buddy! Thank you so much. I confirm it worked perfectly well. As soon as I did exactly what these instructions said, the game launched and worked just fine. Running the game from the original GOG interface has also been fixed.
Long live Dino Crisis.

Is the 'steam overlay while in-game' option on? If it doesn't like the Riva Tuner overlay I'm guessing it might also not like that.

Cheers mate, the RTSS was indeed the problem.

UPDATE to my post here - for better visibility also posted seperately:
RTSS only appears to prevent the launch, but once the game is running, it works fine even with it on.
So after game launch, app can be started again to be able to take screenshots in-game.

Edited immediately after:
To everybody this helped out: You're very welcome of course!
I see your responses, but don't want to clutter the forum unnecessarily by replying to each of you seperately.

To everybody it does not help, unfortunately: Don't give up, it is really a strange issue and I'm hopeful we'll find a solution in any case.

Tried it with the steam overlay on and switched off. Both brought the error.

I just tried it as well - added the game (DINO.EXE) as external executable to Steam and launched it.
I don't get the error regardless whether the Steam Overlay is enabled or not.
Has to be something else.

Short of disabling every application that is normally launched, the ways to determine which app hooks into the game and causes this issue are very limited due to the different ways hooks can be applied.

However, for my above example of RTSS.exe I checked whether the process stands out anywhere as to give an idea that it may be the cause.

I found only one way via another app (so far) to indicate RTSS may be the culprit:

1. Cause the error so the message is currently shown on screen
2. Open the Windows Resource Monitor
%windir%\system32\perfmon.exe /res
(or just via start menu)
3. Go into the CPU tab
4. Put a check mark in front of DINO.exe
5. Look for calls("modules") that are not located either in
- any Windows system32 directory
or
- the game installation directory
(it helps to just click on the "full path" column to sort the entries - see attachment for reference)

Maybe this can help identifying the culprit - atleast in some instances. Good luck.

Guys,

I solved the problem using the code posted by Midoryu with some changes.
I tried to kill RTSS but it stars again immediately after kill it and ther is no time to start the game, then I solved the problem killing both RTSS and MIS Afterburner and after the game starts run both again.

The final code is:

prompt $
@echo off
cls
echo Requires admin privileges, as RTSS runs in admin mode.
echo Ending RTSS to launch DINO.EXE
echo.
taskkill /IM MSIAfterburner.exe /F 2>1>nul
taskkill /IM RTSS.exe /F 2>1>nul
timeout /t 2
start "" "G:\GOG\Dino Crisis\DINO.exe"
timeout /t 5
echo.
echo Relaunching RTSS...
Start "" "E:\Program Files (x86)\MSI Afterburner\MSIAfterburner.exe"
start "" "E:\Program Files (x86)\RivaTuner Statistics Server\RTSS.exe"
timeout /t 8
exit

Works fine to me.
