Just bought and downloaded 3 instrument expansion packs - 1 for Cakewalk Sound Center and 2 for Dimension Pro. The 1 for CSC and 1 of the ones for DimPro were .zip files and worked OK. The other DimPro pack was an .exe file and my computer didn't like it much - said that this isn't a normal type of file download and warned me to delete it. I sent a question to Cakewalk about it to Cakewalk 2 days ago but haven't heard back from them yet. Any insight into this? Should I just download the .exe file and it'll be OK?
