nsExec::Exec won't work with quotes. please help

[mezcalin]

I have share the "Shared Virtual Machines"-folder for the user webGIS
I searched for a tool to make it as simple as possible...found RMTSHARE.EXE.
In the command prompt it works fine:

code:
C:\Daten\Installer\rmtshare \\computer\"Shared Virtual Machines"="C:\Users\Public\Documents\Shared Virtual Machines" /GRANT webGIS:F

But in my nsis-installer the following code will not work, but I don't know why at all.

code:
nsExec::Exec '"$R0 /C C:\Daten\Installer\rmtshare \\$0\"Shared Virtual Machines"="C:\Users\Public\Documents\Shared Virtual Machines" /GRANT webGIS:F"'

the same code for the folder "c:\Daten" will work:

code:
nsExec::Exec "$R0 /C c:\Daten\Installer\rmtshare \\$0\Daten=c:\Daten /GRANT webGIS:F"

I think, it's beause of the quotes, but I don't know how to make it work.
Please help.

BTW: $R0 is initialized by

code:
ReadEnvStr $R0 COMSPEC

Why are you using COMSPEC? COMSPEC is picky about quotes and spaces...

[Afrow UK]

You only put quotes around the executable path, not the entire string. So in this case, just around $R0. And yeah you don't need to use COMSPEC really; just call rmtshare.exe directly.
