Are you on Linux or MacOS?I mean: your computer is not on Windows?
I am asking because the Market does not work for Linux/Mac.
Windows 8?Windows 10?Do you have IE (internet Explorer browser) installed on your PC?
I am asking because some people (who used Linux and Mac) had this MQL4Buy error in past ... and "MQL4Buy + proxy" issue
--------If you bought some product from the market (or want to use demo or any) - try to download directly from Metatrader (not from webpage):
Where can I see my purchases? https://www.mql5.com/en/forum/9950/page70#comment_2564931
How to Install an Earlier Purchased Applicationhttps://www.metatrader5.com/en/terminal/help/market/market_buy
I think, next time - it may be good to buy directly from Metatrader (not from Market page).
