Im asking because i had last night the same problems on a Windows Server 2008 R2 Standard.
First i installed the EA manually,
blah blah dll, blah cannot find toggleDebug, blah'Message error 'Myfxbook.dll' is not 32-bit version''
Then tried it with the EAInstaller. Fail again. Message: 'Cant install Net 2.0 part of Net 3.5 aso'
wtf ?? Why 3.5 ??
Knew i had the newest Version of Net4 on the Server but tried it again to install.
With a external Net4.51installer, Message : 'Your Net4.51 is up to date'
whent to Server Manager -> Add Roles and Features -> found there NET 3.5 Framework ??? (half checked)
checked all of it, installed it, reboot
tried again the EAInstaller,
and voila everything works fine now !
Thats why i asked about using Server..
