#### Cause

This happens because an error was encountered during installation.

#### Fix

If you don't get an additional message to this (like "Couldn't find Excel location!" or "Unsupported Excel version!"), then contact `support@artemisanalytics.xyz` with information about your Windows/Excel versions.

If you get an additional message then check if you have Excel installed and if the version of the installed Excel is minimum 2016.

#### Getting an error message when opening Excel, after the add-in was installed, followed by scrambled text displayed in Excel.

#### Cause

This happens because the wrong bitness add-in file is loaded (32 bit add-in in Excel 64 bit or 64 bit add-in in Excel 32 bit).

#### Fix

While Artemis Sheets installer automatically detects what version of Excel is installed on your computer and loads the corresponding add-in file, if you get this error it can be fixed by following these steps:

* Check the bitness of your Excel, by going to File -> Account -> About Excel

* Open Registry Editor and navigate to `Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Excel\Options`. To open Registry Editor, type `regedit` in Windows Run prompt (Win+R shortcut).
* Locate the OPEN / OPENx key in the right panel that points to `ArtemisSheets-AddIn-packedxx.xll`.

* If the number at the end of the file name (32 or 64) doesn't correspond with your Excel bitness, double-click this key and change this number to corresponding bitness. For example, if your Excel is 32 bit, change the file name in key value from ArtemisSheets-AddIn-packed**64**.xll to ArtemisSheets-AddIn-packed**32**.xll.
* Restart Excel.

If you don't see the Artemis Sheets toolbar in the Excel ribbon, check the following:

* Make sure the [Artemis Sheets Excel add-in is installed](/artemis-sheets/troubleshooting/excel-on-windows-desktop/check-if-the-artemis-sheets-add-in-is-installed)
* You may need to [manually activate](/artemis-sheets/troubleshooting/excel-on-windows-desktop/manually-activate-the-artemis-sheets-add-in) the add-in
