Please see my post on this subject on June 8.
I installed Dashlane on my XP laptop. I couldn't install it on my Windows 7 desktop due to a technical problem: Dashlane was unable to detect my internet connection (a hard-wired, hich-speed connection). It seems to me that their error message was not describing what their REAL problem was. I wrote their support team 2 days ago, but no reply yet.
I installed Dashlane on my XP laptop last night and this morning I UNINSTALLED it! I did not like it at all. I think their problem is that they do not have very user-friendly prompts or instructions.
Although I dd not exactly recommend it on June 8, I can say unequivocally today thet I DO NOT RECOMMEND DASHLANE.
If you try it and like it, please let me know. I would be glad to hear your two cents.
