VS2010

I Uninstalled vs 2016 because it slowed down my entire OS !!!
So, I installed back my trusty VS 2010 but after install, it throw error "Exception has been thrown by the target of an invocation".
Because I installed a newer version of VS than the 2010...

After some time of searching,swearing and spitting, I find that the solution for this problem is: "some [path variable] being longer than 2048 chars" - but they are not specifying where to find this "variable" FILE.

Searching for this [path variable] thing on the internet, I find this "explanation" in a possible solution: """...I ran the following command on cmd line, from the C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE folder:..."""

Now, from what it is describing, he is running a command from a folder, right?
- How to run a command line from a folder? (crying)

Again, thank you.

Try looking at dir command. Type 'dir /?' into a console to get the help. One of the switches, /x, will give you the 8dot3 notations that your computer is using to abbreviate the directory structure. Often, the 8dot3 (8 character representations ARE NOT intuitively just six characters plus '~'). You must reconstruct (construct from C:\) the 8dot3 path using what you find through the dir /x returns ...

To run a command prompt, hold the Windows key, and press "R". Type "cmd" in the textbox, and press ENTER.
When you run a command prompt, it has a "current directory" - this normally defaults to "C:\Users\YourUser" and is shown to the left of the text cursor.

To run a command from a specific folder, you can do one of two things:
1) Specify the folder in the command line:

"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\MyAppName" parameters

- do not forget the double quotes, as they force the command processor to treat it as a complete path, rather than stopping at the first space.
2) Move to the folder first using CD:

cd "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE"

Then run your application:

myAppName parameters
