problem with unity

i had installed unity but after installation the page didnt reload
and when i open pluging menu i didnt find unity tap
if i reload the page by myself it asked me to download and istall unity again
i had uninstalled unity & download then installed unity again ,, no thing change, page not reload and unity not work
i used win 7 64x and firefox browser
( note) i can find unity in program file folder in (C) drive,, and in unstall or change program menu
normaly like other any program

 

So if you click the Unity.exe in the folder, what happens? Any error messages?

 

the folder of unity program in programs file have 4 items Uninstall (app type), UnityBugReporter(app type) , UnityWebPlayerUpdate (app type) , loader-x64 (folder )
the UnityWebPlayerUpdate not open with double click or run as administrator it`s give no thing

 

If you download and run the installer,
http://netstorage.unity3d.com/unity/649f48bbbf0f/UnityDownloadAssistant-5.4.1f1.exe

Then does the installer work?

 

yes and it start to download

 

Then after install, does it show the project selection window when started?

 

unfortunately no ,,, the problem not solved

 

By default, go to C:\Program Files\Unity\Editor and double-click Unity.exe. Then tell us what happens.

Unity also creates a desktop shortcut when installed.

On Windows 10, in the Start Menu it shows recently installed programs... I forgot if Windows 7 has that.

I keep saying this over and over on the forums: PLEASE be specific about what your problem is. Don't just say "it doesn't work", please state what happens after your try to do something. The better you describe your issue, the more answers and help you'll get
