can't omit license dialog

[forestmojo]

hi, wschreyer:

Great thanks for your work, I am using your code. as mentioned in document:
Run python example.py to execute the example script. You may have to acknowledge the dialog showing HEPAK License information (Starting Excel with the Add-In already installed beforehand will suppress this dialog). Then the script will print a few calculated He4 and He3 properties and list some information about the data available in HEPAK.
If I open an excell, then run python example.py, it shows error as following:
C:\Users\Geyang\Desktop\hepak-tools-master>python example.py
Loading HEPAK Excel Add-In. You may have to acknowledge a popup dialog. Launch Excel with HEPAK Add-In already installed to suppress dialog.
Traceback (most recent call last):
File "example.py", line 4, in
print('He4 Standard density:', hepak.HeCalc('D', 0, 'P', 101300, 'T', 273.15, 1))

Thanks a lot in advance.

Hi,
this seems to be some generic error in the win32 COM API. I'm afraid I'm not an expert in that area. Does the hepak Add-In work for you in Excel? You could try some of the simpler functions from the Python module, like HeUnit, HeConst, or HeProperty.
