Thanks for your disponibility.
I just installed Aspen Plus V7.3.2 on a Windows 8 machine and I followed all the installation steps, copying the dll file into the right folders. Unfortunately, as the loading page of Aspen Plus shows up and disappears, nothing else happens.
I tried to install e run apwn.exe with admin rights, but it didn't work either. I don't know what else I can do.
Could you please help me to fix the problem?
