MQL4 missing in Data Foder

[Norbert.27]

I want to add an indicator to the MT4. When I try to open the data folder I cannot find the MQL4 folder. There is an MQL5 folder, if I add the .ex4 file to the indicators folder inside the MQL5, I cannot see my indicator listed in the Navigator. Please help

You have downloaded MT5.
Download MT4 from a broker, not Metaquotes.
