Something not working as expected? Make sure to update your Office first!
If the XL Toolbox does not do what you want it to do, it does not mean that it must be an issue with the Toolbox. You might be able to solve the problem by updating your Excel:
Unable to load DLL files
Some of the XL Toolbox’ features depend on third-party tools. Most notably the graphic export commands require the FreeImage.DLL library. If this or another DLL cannot be load, the Toolbox cannot function properly and some command are disabled.
Usually the required DLL files are installed along with the XL Toolbox add-in, at least if you install the XL Toolbox with the official installer. However, a number of users have somehow managed to circumvent this official installation pathway.
If the Toolbox is not installed in the intended way, it may be installed
by double-clicking on a file called
This will trigger Microsoft’s “OneClick” installation process. It will
install the add-in in Excel all right, but it won’t copy the DLL files
that are needed. You should refrain from using this “OneClick” mechanism
with the XL Toolbox.
If you see a message that the XL Toolbox could not load additional DLL files, please try the following: Uninstall the XL Toolbox via Add/Remove Software, then re-install it using the official installer.
