Most frequent questions and answers

An Excel add-in is a piece of software that adds functionality to Microsoft Excel.  Excel Add-ins are written in Visual Basic for Applications (VBA) or in a compiled language (C/C++). For performance and scalability purposes, we implemented our add-ins (e.g., NumXL, etc.) using C++.

For most enterprises, the default productivity suite of choice is Microsoft Office. According to the latest survey from Spiceworks, 83% of the polled enterprises are using Microsoft Office.

By offering NumXL as an Excel add-in, we are extending the functionality of MS Excel to solve a new set of problems, leveraging your existing investment (Microsoft Office), and eliminating the need for end-users to learn a new tool.

Yes. NumXL tutorials are available online in our support portal and offline in the help file. Furthermore, NumXL installation comes in with numerous examples (workbooks), case studies, and the help file.

Yes, NumXL is compatible with Excel installation of any language. 

Bear in mind that menus, user-messages, and cells’ comments are either in English or Spanish depending on the active language in Excel. English is the default language for non-Spanish Excel.

In Excel, you can manage the add-ins using Add-ins Available Box. To access the Add-in Box, do the following:

  • Click the “File” Tab, and then click Excel Options
  • On the left bar, click on Add-ins
  • On the right pan, Find the Manage Box, Select Excel Add-ins
  • Click GO

To Load an Add-in

  1. If the add-in you want to use is not listed in the Add-Ins available box, click Browse, then locate the add-in.
  2. In the Add-Ins available box, select the checkbox next to the add-in you want to load, then click OK.

To Unload an Add-in

  1. In the Add-Ins available box, clear the checkbox next to the add-in you want to unload, then click OK.
  2. To remove the add-in from the menu, restart Excel.

Note: Unloading or removing an add-in from the menu does not remove it from your computer. To remove the add-in from your computer, you must uninstall it.

Not directly, NumXL requires a Microsoft Windows Based Excel version. However, many of our Mac users install virtualization software (e.g., VMWare) and run Windows on top of Mac. NumXL works perfectly in this scenario, and we currently support VMWare, Microsoft Virtualization, and XEN.

Yes. We currently support the following platforms: VMWare, Microsoft Virtualization, and XEN.

Yes. NumXL works under any Windows account type (e.g. Local administrator, Power user, Limited user, or Guest). The installer program will detect the account-type and permission available to the users. In the case where the user does not have the needed permissions to install the software for everyone, the installer will present one option; to install NumXL only for the current user.

You need to install NumXL (and activate the license key) on each computer, but you may use the same license key; as licenses are issued on a per user basis.

After downloading the NumXL setup (installer) program of the website and attempt to launch the installer, an NSIS Error message pops up: “Installer integrity check failed, Common causes are incomplete download and damaged media”.

Please, check the downloaded file size. If the size is suspiciously small ( less than 1024k), then you have an incomplete download. Otherwise, contact our support line

For incomplete download, please try again, but this time, right-click on the download link, a popup menu is shown, choose the “Save Link as” option and select a folder on your local disk (e.g. C:\temp).

If you have just downloaded NumXL or any of our products, and you receive an error that says that the file is corrupted, or that installation will not start, please make sure that you did not download the product into a network drive. Also, make sure you did not click “Run” when you had the option to “Save As/Save”. Our programs will not start if this is the case. If the situations do not apply to you, please contact our support team and we will look into the matter.

The download starts without a problem, but when the download process reaches 99%, an error pop-up window appears, saying “it cannot copy the file: unable to read the original file or disk”.

Although the download setup program is securely digitally signed, we have experienced this issue with users who sit behind a restrictive firewall or proxy. The problem does not occur when we use a direct link. As a workaround, please email [email protected] and we’ll send you a direct link to the latest product
