How to install old versions of Traktor…?
I need to use an older version of Traktor Pro 2 on my new laptop. I read the article that was up a few weeks ago about this, but it only covers the option of running versions that were installed on your laptop before. I have only used 2 versions on this current laptop, the earliest being 2.7.1.
I need to go back to 2.6.0 to use the Collision Mapping for my APC40.
This shouldn’t be difficult but I can’t seem to find the right link. 
If it’s any use I have 2.6.2 for pc.
a google search found a wares link… but that’s not the way to go.
probably better to do one of 2 things…
get a new mapping or learn and fix it yourself 
or ask NI support for help
There are no NEW mappings, the latest reliable one was made a year ago. I still think that there should be an easy way to revert to old versions of traktor…
And someone should update the APC40 Mappings to 2.8. They are not working properly with the new version.
