Error about the database engine when launching ARRM (from version 1915)

If you encounter the error below when launching ARRM.exe:

Check that you have installed the x64 & x86 Microsoft Access Database Engine 2013 Redistributable
or x64 & x86 Microsoft Access Database Engine 2016 Redistributable

If it still does not work, use the 32-bit version of ARRM that you will find in the ARRM installation directory (available from version 1916 beta 2). The file is called: Arrm_32bits.exe or Arrm_32bits_1080.exe

Error when clicking on eye icons

If when clicking on the icons you get an error message like this:

this means you don't have any application associated with opening .txt file
You just need to configure Windows to associate the opening of .txt files with a text editor (notepad, notepad++ etc…)

Allow ARRM.EXE application in Windows Defender

Windows Defender can prevent ARRM from writing to files used by ARRM located in %appdata%\nexouille Soft\ARRM Like for example the files '_missing_arrm_%SYSTEM%_%SCRAPER_ENGINE%.txt

To authorize the application you have to do the following:

- In Start, find and click on: 'Protection against viruses and threats'
- In 'Ransomware Protection', click on 'Manage Ransomware Protection'
- In 'Controlled folder access device', click on 'Authorize an app via a controlled folder access device'
- Click on 'Add an authorized application'

A choice :

  • Click on 'Recently Blocked Applications', and click on 'Arrm.exe' (or Arrm_32bits.exe)


  • Click on 'Search in all applications' and look for the ARRM.exe executable in its installation folder.

Error regarding the length of a file/folder name greater than 260 characters

The file name and directory name must be less than 260 characters, otherwise an error may occur during certain operations.

However, you can remove this limitation from windows by modifying the registry.
See article: Enable long paths in Windows 10, version 1607 and later

My version is lower than and I don't retrieve any information about Screenscraper

It is imperative to upgrade to version or higher to be able to connect again to the Screenscraper database to be able to scrape.

What operating systems does ARRM run on?

ARRM runs on Windows (7, 8 and 10). It uses .NET Framework 4.5.2 and Visual C Redistributable for Visual Studio 2015. It has been successfully tested on .NET 4.7 and .NET 4.8. It is not compatible with Linux (via Mono or Wine as of May 2019), nor Mac OS.

At launch an error message appears concerning the database

Following a new installation, an error message appears concerning a bad database version.

Solution: you must uninstall the previous version, or use the version without installer, which requires copying the files manually over the previous version. (available here: )

The program crashes on launch or does not launch

  • Since version, ARRM uses windows media player features to display video snaps. If you have disabled Windows Media Player in Windows Features, this will prevent ARRM from launching if your ARRM version is lower than Since version, if Windows Media Player is not installed, video snaps will not display in ARRM, but will no longer cause the application to crash.
  • Remember to give permissions to ARRM in Windows Security:

If you are using Windows Defender, you must allow the ARRM app in Windows Defender. Follow this link: Authorize the application ARRM.EXE in Windows Defender

The program crashes when opening a gamelist.xml

If you get this error message after choosing a system and clicking View:

You probably used the . (period) as decimal separator instead of , (comma) in Windows regional settings. You must use the , (comma)

Since the Beta version: 1900 Beta 8, it is normally no longer necessary to change the decimal separator in the windows control panel.

In Windows 10 here is how to access the modification page of this parameter:

Ratings are not in correct format in gamelists.xml

Since the Beta version: 1900 Beta 8, it is normally no longer necessary to change the decimal separator in the windows control panel.

You probably used the . (period) as decimal separator, in windows, instead of , (comma) in windows regional settings. You must use the , (comma)

In Windows 10 here is how to access the modification page of this parameter:

Under windows 7, the program (controls and texts) do not display completely in the ARRM window, they seem to be too big

You have certainly changed the font size under windows. Right-click on the desktop > Personalize > Display > and choose the size 'Small - 100%' then click on 'Apply'.

Under windows 10, the program does not display texts and forms correctly

Example of display problem you may encounter:

You have certainly changed the font size under windows.
Stop ARRM, Go to 'Settings', 'System', 'Display', and put '100% (recommended)' in 'Scaling and Layout'.
Note: If before these manipulations ARRM is not stopped, the change will not apply to the program.

You can also, to change the settings only for the application, do

  • Right click on the ARRM app
  • Property
  • Compatibility
  • Click on 'Change high DPI settings
  • Check 'Override high DPI scaling behavior' and select 'System' from the drop-down menu
  • Click OK


Thanks to Titruf for this solution

Maximize windows via 3rd party software

If you want to enlarge the windows (which are not resizable by default in ARRM) it is possible to use an EnableResize program, which can help. Please note that some controls may be in the wrong place. Thanks to André Braga for the information on this program. Link : ResizeEnable

Under windows 7 32 bit, the program displays an error message regarding vcruntime140.dll
