MT4 and Vista

LanBar

I am using Vista Business and never had any problem using MT4, in fact I am using accounts with Two brokers and both of them are working fine.

I suggest you back up all your custom work "if any", such as Template, Script, Experts, Sounds, etc. then unstall the MT4, delete the folder and subsequent folders where u have ur MT4 installed, restart the computer, download the MT4 from ur broker website "preferably saving the download to ur computer rathet then directly opening/running download", reinstall and see, I hope it solve the problem.
