...and yet you were right, the config file I showed you above has the correct value, but the "options" menu you wrote had the incorrect setting. It's really strange but, hey, now it works. Thanks a lot!

I don't think so. In my config file I see this segment: <setting name="PuttyLocation" serializeas="String"> <value>C:\Program Files (x86)\PuTTY\putty.exe</value> </setting>

You're probably right, where can I fix this? I uninstall PSM and reinstall it, and it never asks me the question, and when I start it it remembers the tree structure for my sessions, so apparently the uninstall doesn't do a clean job, and part of it is the incorrect path that persists.... The PSM folder is removed from Program Files (86) but the registry may be corrupted....
