thanks again for your support,
actually something is missing as i cajn't find the bitnami console entry, only install/start/stop/unistal bitnami redmine stack as a service
Start -> Bitnami APPNAME Stack -> Application console is missing
The current redmine-2.6.0-1 is on a 2012R2 STD windows env while the new 4.1.0-8 is on 2016 STD
C:\Bitnami\redmine-4.1.0-8\apps\redmine\htdocs>C:\Bitnami\redmine-4.1.0-8\ruby\bin\ruby bin\rake db:migrate RAILS_ENV=production
Traceback (most recent call last):
2: from bin/rake:29:in
<main>'block in replace_bin_path'
1: from C:/Bitnami/redmine-4.1.0-8/ruby/lib/ruby/site_ruby/2.5.0/bundler/rubygems_integration.rb:493:in
C:/Bitnami/redmine-4.1.0-8/ruby/lib/ruby/site_ruby/2.5.0/bundler/rubygems_integration.rb:462:in `block in replace_bin_path': can't find executable rake for gem rake. rake is not currently included in the bundle, perhaps you meant to add it to your Gemfile? (Gem::Exception)
I'm gonna ask to my leader about the plugin.
