Notation Software is the first program that gives me that type of headache. I am sure Vista is not the "problem".
When I run Notation Composer with administrator rights for all users the "
first run" problem does not occur.
In my opinion Notation software has
issues concerning rights management on Win x64 and not especially on Vista.
Have Notation Software installs been tested on Vista x64? It's not me who claims Notation Software to be "Vista compatible"... 
Don't misunderstand. I am not complaining about anything. I wouldn't take any effort to fix things if I didn't like the program itself. I just want to get all fixed proper. The workaround suggestions I've seen here so far seem not to address the real issues IMHO.
I have no machine running Win 7. So that's no option for me.
So no fix ideas on Notation Composer Vista x64 installation?
