Installation/Uninstallation

Installation/Uninstallation

Installation of Cam2Com is based on Microsoft Windows Installer (MSI). The installer itself is not included in the distribution package; it must already be present on the target operating system (Windows 2000, XP, Vista and up).

To install Cam2Com:

First of all make sure you can connect your camera to USB port and download some pictures. You may need to install camera driver for that.

Log on as Administrator or a member of the Administrators group.

Double-click on the Cam2ComM.msi file and follow the instructions.

Cam2Com can be found in the Start Menu in the Programs|Sabsik item.

Do you need to install a driver?

The table below summarizes which cameras need Olympus driver for different operating systems.

Camera	OS
Camera	Windows 2000	Windows XP	Windows Vista
*Olympus "Rye" cameras*	Not needed	Not needed	Not needed
*Olympus "Wheat" cameras*	Driver from the CD that comes with the camera	Driver from the CD that comes with the camera	Not supported
Canon CD cameras	Driver from the CD that comes with the camera	Not needed	Not supported

If you need to install the driver, connect the camera to a USB port and wait for "New Hardware wizard" to start. Then follow the instructions. When prompted to find the driver, select "have disk," navigate to the "Drivers" folder of the Camedia installation disk, and open it. Select the folder for your operating system and continue with Wizard.

To uninstall Cam2Com:

Follow the standard Windows procedure in Add/Remove Software in the Control Panel.

Changes Cam2Com makes to the computer system:

Creates a directory where it is installed with necessary files. Usually it is "C:\Program Files\Sabsik\Cam2Com", but a different path may be selected during installation.
Creates a Cam2Com directory under "My Documents" with files containing camera settings, etc.
Creates a Cam2Com directory under "Application Data" in the profile of the current user for configuration files, error log, etc.
Registers "Wheat" ActiveX control.
Adds Registry key HKEY_CURRENT_USER\SOFTWARE\Olympus\Rye (if it is not there yet)
Adds Registry key HKEY_CURRENT_USER\SOFTWARE\Sabsik\Cam2Com with a few entries like last used settings, etc.
Adds Registry key HKEY_LOCAL_MACHINE\SOFTWARE\Sabsik\Cam2Com with a few entries like version, license, etc.
Adds itself to the Start Menu.
If you select to install OlymRye.sys pass-through driver (it is default), then the driver is registered. Driver files are located in the Cam2Com installation directory and OlymRye.sys is installed into %SystemRoot%\System32 directory as shared file.
MSI saves uninstall, etc. information for its own use.

Other than that, properly installed Cam2Com does not modify anything on the computer. Olympus "Wheat" ActiveX control adds a few more Registry entries by itself.

Interactions with other software using Olympus SDK

Wheat.ocx

Cam2Com registers Wheat.ocx - Olympus ActiveX control for use with the "Wheat" SDK cameras. When Cam2Com is uninstalled, it unregisters this ActiveX and deletes it from the computer.

If some other software also uses this ActiveX, it also registers it during installation and unregisters during uninstallation. Despite the fact that these Wheat.ocx files are most likely located in different places in the file system of the computer, they are registered in the same place in the computer Registry as COM components. So, after the uninstallation of any such program, most likely the Wheat.ocx of other programs will be around but no longer registered and will stop working. To make it work again, either reinstall the software that you still want to keep (as a part of the installation it will re-register Wheat.ocx) or find it on your computer and register manually, using the following steps:

Run cmd (press Start button, select Run, then type cmd and press OK)
Switch to the folder where Wheat.ocx is located (for Cam2Com it is normally C:\Program Files\Sabsik\Cam2Com) by typing: cd C:\Program Files\Sabsik\Cam2Com
Use RegSvr32 to register Wheat.ocx:
regsvr32 Wheat.ocx

Olympus "Rye" and Canon CD SDKs installed by the other software are not affected by installation or uninstallation of Cam2Com.

OlymRye.sys

OlymRye.sys is a pass-through driver from Olympus. This driver allows regular, i.e. non administrator users to use Cam2Com with Olympus "Rye" SDK (SDK 3.4) cameras. If the driver is not installed, you have to log on as and administrator to be able to control those cameras.

This driver is registered as a service, and thus shared between applications. If two applications register the driver, the last one wins, and the driver runs from the location specified by the last application. But if any of the applications unregisters the driver, the driver gets unregistered, and the other application is affected. Because there is no coordination between applications on the way how the driver is installed, it can get wrongly unregistered when uninstalling an application. In another application will stop working unless administrator account is used, reinstalling that application most likely should help.

Cam2Com has a special utility, OlumRyeConfig.exe, that can register and unregister OlymRye.sys driver. So, if after uninstalling other software that worked with Olympus "Rye" cameras Cam2Com stops working with the "Rye" cameras, try the following:

Log on as administrator and try to run Cam2Com and acces a camera. On Vista you also need to run Cam2Com "as administrator".
If Cam2Com works, you need to reinstall OlymRye.sys driver:
In the Start->Sabsik->Cam2Com find OlymRye.sys Configuration and run it.
The application shows the dialog - click "Install OlymRye.sys" button.
Close the application, log out and log on into your normal user account. Cam2Com should work now.
