Hello All, After some testing, and after Per took the time to write out a detailed instruction of how to open the installers for the pskmail clients, I have discovered something interesting. I was unable to open the installer and I am still unable to open it, but he is what I have found. On both my Windows XP machines both the 1.5.9 and the 1.5.10 installers will open immediately and do a full install of the client in under a minute. But, on both the Vista and the Windows 7 machines they will not open, not even in the terminal using the linux commands that Per was so kind to post on his web page. I am totally baffled by this result. I know that others may be able to open them with no problem, but not here. Very 73 to all, Glenn WB2LMV
