install on SU 2013 and 2014

on my computer windows 7 sketchup 2013 and 2014 are installed.
I installed plusspec.
He is active with SU2013 but not SU2014,
yet he appears well on the window “system preferences” of SU2014
why is it impossible to run su 2014?

Try dragging and dropping a file on your desktop and opening from the desk top.
Sketchup is working on this problem.
I use PlusPec every day in Sketchup 14 . Unfortunately this is the best work around untik our friends over at Sketchup release the next update. Fingers crossed.
Let us know if this fixes your issue. Thanks for asking.

Hi Andrew,
thank you for your reply,
I tried your suggestion but it does not work on SU2014

I also have a problem on sketchup 2013: loading tools
see item exchange with DanielB here:
viewtopic.php?f=12&t=139&p=342 # P342

may be that everything is connected?
is that it is possible to SU2013 and 2014 on the same disk c: and combine with plusspec working?
Currently I am completely stuck.
thank you for your response
