[German<\/a>]Another addendum from November 2024: On November 19, 2024, Microsoft fixed a problem caused by the security update KB5002653 from November 12, 2024 in Microsoft Excel 2016 (MSI version). Add-ins could no longer be loaded there.<\/p>\n

The Excel 2016 add-in loading problem<\/h2>\n

\"\"On November 12, 2024, Microsoft released the security update KB5002653 for Microsoft Excel 2016 (MSI version) to close various vulnerabilities (see Patchday: Microsoft Office Updates (November 12, 2024)<\/a>).<\/p>\n

This security update is intended to close the Remote Code Execution vulnerabilities CVE-2024-49026<\/a> (Improper Neutralization of Special Elements used in a Command ('Command Injection')), CVE-2024-49027<\/a> (Use After Free, CVSS 3.1 Score 7.8), CVE-2024-49028<\/a> (Out-of-bounds Read), CVE-2024-49029<\/a>\u00a0 (Use of Uninitialized Resource) and CVE-2024-49030<\/a>\u00a0 (Heap-based Buffer Overflow). All of the RCE vulnerabilities were rated as important with a CVSS 3.1 score of 7.8.<\/p>\n

However, this security update caused a huge problem. A blog reader contacted us by email on November 13, 2024 and noted that after installing the KB5002653 update, no add-ins were loaded when Excel was started. Since the installation of the Office updates for Office 2016, Excel has been trying to load add-ins when entering the path, for example:<\/p>\n

\"C:\\Users\\username\\AppData\\Roaming\\Microsoft\\AddIns\\\"<\/pre>\n
to load the file LASSIST.XLA, although it was actually named \"VLASSIST.XLA\". Excel truncated the first letter of the path to the add-in so that the file could no longer be found.<\/p>\n
Microsoft subsequently acknowledged the error and promised a remedy. I described the problem in more detail in the blog post Excel 2016 can no longer load add-ins after Nov. 2024 update KB5002653<\/a>. Various workarounds are also described there to be able to load add-ins after all.<\/p>\n
Update KB4484305 fixes add-in loading error<\/h2>\n
Microsoft has released the update KB4484305<\/a> for Microsoft Excel 2016 (MSI installer) on November 19, 2024. According to the release note, the update fixes the problem that activated Excel add-ins could not be loaded correctly when opening Excel after installing the November 2024 security update. This update passed me by – a reader posted the information<\/a> in a comment (thanks for that).<\/p>\n
The update KB4484305 is only available for Microsoft Excel 2016 in the MSI installer version. The download links for 32- and 64-bit Excel versions can be found in the support article.<\/p>\n
