After installing ArcGIS Desktop using the 'Register now using the Internet (Recommended)' option to authorize the software returns the following error:
![[O-Image]](https://webapps-cdn.esri.com/CDN/support-site/technical-articles-images/000010525/00N39000003LL24-0EM39000000wdAr.png)
Cause
This error is generated when European language characters, such as the umlaut (e.g., �), are used to fill out the parameters required for registering ArcGIS Desktop over the Internet.
Solution or Workaround
There are two ways to work around this issue:
- Visit service.esri.com, and select the 'Product Registration' tab, register ArcGIS online, and receive an authorization file by way of e-mail from ESRI. Use the authorization file to complete the registration of ArcGIS Desktop using the option 'I have received a license file from ESRI and am ready to complete the registration process' in the Desktop Administrator.
- Do not use European characters such as umlauts when registering ArcGIS Desktop.
