This is a general drawback in many Windows programs. Upon installation they
copy DLLs all over the system and manipulate the registry. When you have to
install the system anew because of a crash ( and I had severl even with NT
though thats more stable) programs won't work because they are so spread over
your drive. It doesn't matter that your installation files were never hurt you
have to reinstall to be sure that everything works again. Funny thing is, when
I had this problem I forgot to reinstall GhostView. After I started it it
detected that there is something wrong and registered itself again, so there
was no need to reinstall the entire package. An option I miss in many Windows
programs. That's why I prefer programs that keep their stuff to itself. When
you want to delete it, simply delete the directory and you are rid of it. When
you need to copy it simply copy the directory tree and you have it. When you
want to copy MS Office to another machine there is no way but installing it
new and loosing all changes you made to your previous installation.
