Uninstall a sofware with registry uninstall string from Control Panel

Hi,

I created that registry key (export from registry to reg file):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\!Vcredist2005_Frv1]
"DisplayName"="!Vcredist2005_Frv1""DisplayVersion"="2005""InstallDate"="2015-02-05""Language"="Fr""Publisher"="""UninstallString"="powershell -executionPolicy bypass -noexit -file \"C:\\Program Files\\xxx\\yyyyyyyyyyyyy\\zzzzzzzz\\Vcredist2005_Frv1\\Vcredist2005_Frv1_DesInstMan.ps1\"""NoModify"=dword:00000001"NoRepair"=dword:00000000"NoRemove"=dword:00000000

Everytime, I am trying to uninstall the software, I get an error saying the software seems to not being intall. At command prompt the command line is not working. I would like being able uninstalling software from control panel.

Any idea of what I am missing?

Thanks,

François
