Run Dia localy

Python
1

Hi,

I have downloaded and extracted the dia_pkg_1.3.8.zip. Like in the started guide, i try to run dia from cmd.exe. I receive the error message below. For me, it’s difficult to understand the problem. Could you help me?

Thanks.

I may be completely wrong here, so someone correct me if thats the case. Try installing the PyWin extensions (make sure you grab it for the correct version of python):

http://sourceforge.net/projects/pywin32/

Which version of python are you running? 2.4?

The PyWin extensions is always a good idea on a Windows machine (I’ve always preferred the IDE it offers, less like a UNIX editor).

I believe to run the CONSOLE presentation, you also need pyserial … but I do think Dia includes this already in the src/lib/serial directory.

As per our Dia online documentation:

Note
From iDigi Dia 1.3 onward, to run it on a PC you must install pywin previously. Please, install pywin for Python 2.4. It may be downloaded from this link:
