Error with PDN Tool 2.0 for Cyclone V

Hello,
I'm trying to use the PDN Tool 2.0, version 16, build 04.27, for Cyclone V.

After starting the tool, I keep getting the following error message:

Runtime error 53
File not found: 28nm_pdn_16.0_hid_04_27_32bit.dll

I'm using Excel 2016.

Does anyone have any idea how I can fix this problem?

Thank you in advance.
Matthias
