Just one last question.
The logical order must be
1)
I ran jf18_fix.
I un-installed the version 1.7
I installed the version 1.8
I un-installed the version 1.8
I installed a second time the version 1.8
or
2)
I un-installed the version 1.7
I ran jf18_fix.
I installed the version 1.8
I un-installed the version 1.8
I installed a second time the version 1.8
or
3)
I un-installed the version 1.7
I installed the version 1.8
I ran jf18_fix.
I un-installed the version 1.8
I installed a second time the version 1.8
