[CY_10812282]

Good evening community, I have a problem with the combo box tool, it turns out that I want to use this tool and I get the error that I show below, Install Mathcad Prime 8.0.0, on a Windows 7 operating system, if someone can give me a reason for this error.

Buenos diaz.

The error message is handled here: https://community.ptc.com/t5/Mathcad-Installation/Error-quot-An-Unhandled-exception-occurred-on-the-dispatcher/m-p/706410#M19

Pay attention to language: It appears that the error can occur if the language version of your Prime installation is different from the language of your Windows.

You can start Prime in a different language, see here: https://community.ptc.com/t5/Mathcad-Installation/Switching-language/m-p/744327

Succes!
