Is it safe to delete all Microsoft visual c++

There is nothing dangerous about it so I guess that would make it safe - but some things might stop working:

When developers write their programs they might use any one of the versions of Visual C++ to write them.

When you install those third party programs it would be nice if the installation package included the C++ runtime libraries you need to get them to work but that is usually not the case.  And these developers often don't list in their program requirements section what C++ runtime libraries you need to have installed to get their stuff to work.

Sometimes I think they believe that just because the program installs and works fine on their system it will install and work fine on every other system on the planet.

The C++ runtime libraries are not included with a Windows installation either.  This is why when errors about missing runtime DLL files pop up it makes no sense for the Microsoft engaged alleged "experts" to suggest running sfc /scannow (but they keep doing it anyway).  SFC doesn't know or care about any of those files.

Instead of you having to install the entire C++ on your system you can just install the redistribubtable runtime libraries which is usually a bunch of DLL files.

If the needed runtime libraries are missing from your system you will see something like this popular message from Skype:

And you can tell that it is a Microsoft Visual C++ file that is missing since the file name begins with MSVC...  but you can't tell which of the C++ runtime libraries you need to install.

So you need to figure out (from somewhere) which C++ redistrubtable you need to install to get the program to install and run without complaining.

With Skype it turns out you need the 2015 redistributable:

Over time you may find you have several redistibutables installed and that is not a problem:

If you uninstall them some program on your system is liable to quit working and I don't think there is a good way to figure out which third party program you have installed that is going to quit working after you uninstall them.

Nobody here can tell you what/which Visual C++ Redistributables you might need to have installed on your system.

Note that with a clean install of Windows there are no Visual C++ Redistributables included.

The third party programs you install later might need a certain redistributable for the program to launch/run.

If you uninstalled a C++ redistributable and your autocad doesn't work anymore you probably need to reinstall that C++ redistributable.

You have to check with the WWW site or support pages of the third party programs you install to see which C++ redistributable you install need.

If you need help you need to better describe what "doesn't work" means and if you are getting some error messages check with the support page of the autocad program and see what they have to say about it.  Saying "doesn't work" isn't going to get you much help.

Some older programs might need older versions, some newer programs will need later versions and over time you might see that you will need to have several redistributables installed:

Here are some examples of third party programs that will not launch/run without at least the 2015 redistrutable installed:

After installing iTunes it looks like this:

Using Skype as an example:

But again, is it a problem if I only have Microsoft visual c++ only to 2008

Ok thanks, i kinda panicked a little bit but I'm sure its alright :D

and some programm like autocad is stop working normally ( lagg/need some more time by rendering), after i ve deleted some Microsoft Visual C++. is it because i have deleted this microsoft visual c++ or?? please help, i need my autocad
