HI again Leonardo, answering your question : install in a new clean directory.
When the error HistoryCleaner happens and its installation aborts, in the new directory are present only 2 dirs : Settings and Uninstall and 2 files JV16pt.exe and recognition.dll.
Further I have recalled that one full installation of the last jv16 program v.2001053 has occurred on 31 july of 2011, but that program works with lot of errors. :?
I have found also an error bug-report file in the jv16 dir on XP-OS, strange that no one from the jv16 support has asked to send it in the previous emails exchanged.
And I own 2\two jv16 licenses. :
I have also tried on a Win7pro-italian and there all the installation procedure has run errorless.
Will test on it for run errors, now I know where the bug-report is, but I cannot understand where ot what errors it reports.
I am also ready to upload to the support the bug-report if they will ask for.
Regards.
Filippo
