Thank you for using the currency converter! This page answers some of the most frequent questions users may have with the currency converter.

I cannot see the addin.

The addin is not really visible in Excel. When it is installed, you can use the new formular, try entering e.g.:

=CX(100,"USD","EUR")

To convert 100 USD to EUR. If it works, the addin is installed. If Excel says “unknown formula”, the addin is not installed. If there is an error message e.g. “no internet connection”, check your internet connection. In case you use a proxy server, you need to buy the professional version.

How to activate the professional version / where to enter the serial number?

Use any of the pro features in order to activate the professional version. E.g. you can use the following formular to show the popup where you can enter the serial:

=CX(100,"USD","EUR","11.11.2011")
