I’ve got the different error: it looks for file Dose fo Excel.dll within download folder, which is Application Files\Dose for Excel_3_1_7_5, and there is no such a file in that folder, so no wonder it throws an error. There is only one file in that folder, Dose for Excel.vsto, and that same file is also in root folder, too.
So, something is dodgy with installation, which is pitty, as program features sound very nice. Hope they will see these complaints and fix it!
My bad on this, sorry – these files do exist in download file, but for some reason, UltimateRAR does not unpack them when I unpack the entire folder – I have to go inside that folder and unpack files manually one by one.
So, installed and registered, it works fine. Thanks to SoS and producer of this software!
