I run a German version of Win 7.
( the comment in the title is just to attract the attention of any possible German readers)
I tried to install Fences 2.0 (full version) over a Ver 1 (also full version).
It requested that I de-install Ver 1. OK - Done.
I installed Fences 2 - it crashed or rather did not really start.
I have forgotten what the MS standard message is in English - probably something like - programme has an error and has been closed.
I removed Fences 2.0 and made a cold start - twice just in case - Did not help.
My luck was that I read the Forum before installing Ver 2.0 and therefore took out the time to make a real "Full Backup".
I am now back on Ver. 1 and will write off the 7 bucks to experience.
Pity - I think the programme is great and was looking forward to exploring the new functions.
It may well work on other systems - but I recommend the Backup !
