No, Inviska software does not contain anything that could compromise the integrity of your computer, your security or your privacy. Specifically it contains:
Inviska applications periodically check for updates so they can notify you when a new version is released. No information is sent from your computer; the software simply reads the latest version number from this file on the Inviska website. If you do not want the software to connect to the internet the behaviour can be disabled entirely (seen next question).
Yes, this behaviour can be disabled in the Preferences dialog under the General settings:
The first option will check for new releases and display a notification once, and only once, each time a new version is released.
The section option will check for new versions, and the latest version information will be displayed in the Help -> About dialog.
The third option disables update checks entirely, so the software will make no attempt to connect to the internet.
Settings are stored in an .ini file which is named after the application (e.g. InviskaFileManager.ini, InviskaRename.ini, etc). The location of the settings file depends on the operating system and version:
|Version||Config File Location|
|Windows Portable||In the application directory.|
|Mac Portable||In the .app bundle under /Contents/MacOS|
|Linux Portable||In the application directory.|
Very few people use 32bit Linux, with one major distribution saying that only 5% of their users used the 32bit version. Some distributions, such as openSUSE and Arch, are no longer offering 32bit versions, and with the vast majority of processors now supporting 64bit, it appears time to move on from 32bit.
It should run on most common distributions, and I've yet to encounter a distribution that it won't run on. The current 3.0 release has been tested to run without additional dependencies(*) on:
(*) The MKV applications are dependent on MKVToolNix, so that will have to be installed.
There are a small number of rarely used codecs that are not supported for extraction. Any files that contain unsupported codecs will have their names rendered in red. The tracks which use the unsupported codecs will also be coloured red:
The box next to such tracks cannot be checked, and the tracks will not be extracted as part of any batch extraction jobs.
The following codecs are not supported:
|V_MPEG4/MS/V3||Microsoft MPEG4 V3|
|A_PCM/FLOAT/IEEE||PCM Floating Point|
It is unlikely you will encounter these codecs in an mkv file, as they are not commonly used.
