Hello Sergey
...
>> Just by using

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VFPSrv\Parameters]
"AppDirectory"="d:\\fox90\\test"
"Application"="d:\\fox90\\test\\vfpsrv.exe"
"AppParameters"="myparm1 myparm2"

actually didn't work.

A service with no params - I can't get registered - any ideas?

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PDNC_JS\Parameters]
"AppDirectory"="C:\\Kapps\\Chanel"
"Application"="C:\\Kapps\\Chanel\\PDNC_JS.EXE"

Error is
can't import C:\temp\chanel2NTSrv.reg: The specified file is not a registry script. blah blah
