I tried to install ZennoPoster on my Windows 2008 R2 Server with .NET 4 but it throws error "Zenno LAb Product installer has stopped working" after unpacking files. I have tried to reinstall .NET but it didn't help.
I have turned on .NET 3.5 and the program installed fine. But now I have another problem - ZennoPoster doesn't start. When I try to start it, the text "Starting program..." appears and after few moments it is gone and nothing is started. On task manager Projectmanager.exe starts and after some time it dissapears.
Think I had this message once when I was already running zenno (on another pc or the same pc)
Make sure you haven't have it running on another pc or that it isn't already running in the background. (check task manager).
