Office: There’s not enough memory or system resources to start

Symptoms

Error messages when selecting a .docx/.pptx/.xslx file in Windows Explorer preview pane:

There’s not enough memory or system resources to start PowerPoint
There’s not enough memory or system resources to start Word
Excel displays an error message with a red cross icon and no text

Solution

This happens when the 64-bit version of Microsoft Office 2013 or Microsoft Office 2016 is uninstalled and the 32-bit version is reinstalled. This leaves references in the registry for 64-bit Preview Handlers.

To fix these errors and repair the preview pane, run Regedit as administrator and delete these registry keys:

Microsoft Excel previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{00020827-0000-0000-C000-000000000046}

1	HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{00020827-0000-0000-C000-000000000046}

Microsoft PowerPoint previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{65235197-874B-4A07-BDC5-E65EA825B718}

1	HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{65235197-874B-4A07-BDC5-E65EA825B718}

Microsoft Word previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{84F66100-FF7C-4fb4-B0C0-02CD7FB668FE}

1	HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{84F66100-FF7C-4fb4-B0C0-02CD7FB668FE}

Microsoft Visio previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{21E17C2F-AD3A-4b89-841F-09CFE02D16B7}

1	HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{21E17C2F-AD3A-4b89-841F-09CFE02D16B7}

A logoff/logon or reboot is required.

Convertir toutes les tables MyISAM en InnoDB chez Infomaniak

Chez les hébergeurs mutualisés, comme Infomaniak, les serveurs de base de données MySQL sont souvent configuré pour créer des tables au format MyISAM par défaut. Comme Infomaniak supporte les tables InnoDB dès MySQL 5.5, il est possible de les convertir manuellement en 2 étapes.

1. Lister les tables MyISAM

Remplacer nom_de_la_table par le nom de la table:

select concat('alter table `', table_name, '` engine=InnoDB;')
    as sql_statements
from information_schema.tables as tb
where table_schema = 'nom_de_la_table' and engine = 'MyISAM'
    and table_type = 'BASE TABLE';

select concat('alter table `', table_name, '` engine=InnoDB;')

as sql_statements

from information_schema.tables as tb

where table_schema = 'nom_de_la_table' and engine = 'MyISAM'

and table_type = 'BASE TABLE';

2. Exécuter la query générée précédemment

Note qu’avec phpMyAdmin il faut d’abord cliquer sur Options et sélectionner Full Texts.
