not_always_the_newest

after win 10 is started one error message is coming [Window Title] C:\Program Files\WindowsApps\SinewSoftwareSystems.EnpassPasswordManager_6.60.770.0_x86__fwdy0m65qb6h2\EnpassStartup\EnpassStartup.exe [Content] "C:\Program Files\WindowsApps\SinewSoftwareSystems.EnpassPasswordManager_6.60.770.0_x86__fwdy0m65qb6h2\EnpassStartup\EnpassStartup.exe" konnte nicht gefunden werden. Stellen Sie sicher, dass Sie den Namen richtig eingegeben haben und wiederholen Sie den Vorgang. So I don't know, what is missing. Enpass is running, but to each start of Win this message is coming.

I use Firefox V56.x because some Addons and features that don't have the new versions... I forgot to configurate to "no updates" and yesterday morning it's happend. Desktop is V5.6. and extension is V6.0 and they don't work together. So I like to download again the extension for Firefox before V57.x. but since yesterday with coming V6.x of enpass, all "old" downloads away. Where can I find the old one?
