Registry tweak in RunOnceEx.js

[homeless]

I need some changes in registry when windows installed.
I use reg-file in catalog - %CDROM%\Software\Tweak Registry\tweak.reg
and in "Software" tabs in WUCD i add command line for adding this
file to registry. In file RunOnceEx.js i see line:

soft[n] = new Array();
soft[n].name = "Tweak Registry";
soft[n].checkPoint = "Software\\Tweak Registry";
soft[n][0] = "regedit /s \"%CDROM%\\Software\\Tweak Registry\\tweak.reg\"";

BUT in installation i have error message in this file in line 95 pos 4
"file not found"

Can some solve this ?
(may be all problem in command line for regedit ?)

P.S. - sorry for my english - it's not my native language
