Can We install both mt4 32bit and mt5 (new) on window 10?

 

After I install both mt4 32bit and mt5 (new) on window 10.

I do not see mt4 32bit running and 

But I do see mt5 running very well

 
Are you sure that you installed MT4 on Windows 10?
Because if you want to install MT4 so you should download MT4 from the broker's website (MQL5 website does not have MT4 to download and install).
 
Yes you can install MT4 downloaded from your broker and also MT5 downloaded from MetaQuotes website.
It will work perfectly
