Installation Details
This section describes the actions the setup utility performs to install the API
and OCdriver.
If you select Runtime (Complete), the setup utility:
1. copies the device driver file,
OCdriver
, to the system device driver directory
(
%SystemRoot%\system32\drivers
).
2. adds this key and these values to the system registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\OCdriver
ErrorControl: REG_DWORD 0x1
Group: REG_SZ Extended base
Start: REG_DWORD 0x2
Type: REG_DWORD 0x1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Drivers\ OCdriver
EventMessageFile= REG_EXPAND_SZ%SystemRoot%\System32\Drivers\OCdriver.sys
TypesSupported= REG_DWORD 0X00000007
3. copies the library file,
OCapi.dll
, to the
%SystemRoot%\system32
directory.
If you select Runtime & Development, the setup utility performs the same steps as
for Runtime only and the setup utility copies
ocapi.lib
,
ocapi.h
, and the sample
source files to a development directory.
