I posted pretty much the same problem about a year ago when I bought MailWasher Pro. Here's that post, revised to update it:
...and it worked just fine on my Windows 7 Toshiba laptop. Then it started NOT working--not starting on bootup and NOT starting when I clicked on the desktop icon shortcut. After a few exchanges back and forth with support at Firetrust, it started working again after minor tweaks and then stopped working....and then started working erratically...and then stopped. Clicking on the desktop icon did nothing.
Firetrust suggested I upgrade the Microsoft .NET program from the computer. After doing so, MW Pro worked as it is supposed to, but now I'm back to it not automatically starting on bootup.
I have uninstalled the program and made sure I installed he current version.
Some other info that may help a supertechie help me: I have ESET NOD32 installed (have used it for three+ years) and it starts automatically on bootup. Never had a problem with it. Also, the dropbox icon appears in the toolbar, so I'm guessing it, too, starts on startup, And ditto for Ion Restorer. Although, MailwasherPro DID work for a few weeks with all of these apparently also loading, and there were no conflicts.
Finally, and this may not be related at all, but I don't know, so I'm mentioning it here: ESET is due to renew in a few days, so I'm getting the reminder notice automatically appearing on bootup.
Does ANYONE have any suggestions on solving this hassle? I must admit I'm looking for replies from experts who have experience in this type of thing and not suggestions that anyone can find with a few Google searches.
