run file with variable and spaces in variable

Hello,
 
I would like to execute a file on a server. The path to the file contains spaces. It´s not possible for me to change the folderstructure... - When I put the whole path and filename with quotations in the shell.run method it works, but I would like to use variables for that and other cases. Here my construct and what I tried:
 
When I use
shell.run """\\server\Software\Internet Explorer\IE8" & "\IE8-WindowsXP-x86-DEU.exe""", 0, True
it works. File will be executed.
 
I would like to have something like the following:
 
parta = "\\server\Software\Internet Explorer\IE8"
partb = "\IE8-WindowsXP-x86-DEU.exe"
 
shell.run ""parta" & ""partb"", 0, True
 
And this does not work... Could anybody be so kind and tell me what I´m doing wrong and how I can get it to work? Is it possible to do it in that way?
 
Thanks for your help!

Then establish the a reusable code fraqment for using .Run or .Exec
Dim sCmd : sCmd = ...to be filled...
WScript.Echo sCmd
.Run sCmd, 0, True
Then combine Quotes + parta + partb + Quotes, e.g.
sCmd = """" & parta & partb & """"

Hello again,
 
thanks for your help!
The following did the trick right now for me:
 
shell.run """" & parta & partb & """", 0, true
 
where variable parta contains a path with spaces.
