I installed Olympus DSS player (version 6.3) on my HP with windows vista home premium OS. The DSS player works fine, but I am not able to use the corresponding RS25 foot pedal with it. Please help!

Vista sucks anyway, and anything that can run Vista should be able to run Windows 7. This is a blessing in disguise. Buy Windows 7 Home Premium Upgrade and install it.You legally qualify for the upgrade version if your computer came with Vista. You can use instructions here to make the upgrade version work on a clean disk:http://windowssecrets.com/top-story/clean-install-windows-7-from-the-upgrade-disc/

If you have version 6 installed.
Download version 7 and all its updates which is a free upgrade then simply goto help and updates
do the updates for version 7 and hey presto the foot pedal will work.

The AS2300 foot pedal RS23 or RS25 are not compatible with 64 bit operating systems. You will need an RS27 pedal, available at http://www.dictationmall.com/147-035.html

Also the software is not supported on windows 7. You can get a free upgrade to the latest version, dss player standard, here. http://olympusamerica.com/cpg_section/software_results.asp?id=1219&os=w

If you have version 6, you need to upgrade to version 7 first. Once at version 7, you can then upgrade to player Standard.

Yes, if you use a Virtual Machine, you can install the version of windows you wish to work with, install the software, and it should work just fine.
You will however need a genuine copy of windows to install in the virtual machine.
You may be able to find an image of the OS you need, or a snapshot of an OS, to load into the VM, it all depends on the type of VM you are going to use

The Olympus VN8500PC works perfectly with Mac or OC

Try running in compatibility mode for the program. Go to the program thru Start menu, then right-click. There you will see the compatibility mode Tab or choose properties.

The product key on the label on the bottom of the laptop will only work for the version of Windows that was installed on that laptop.
You can purchase an upgrade Windows Vista Ultimate and to use in conjunction with the existing Vista Home Premium.

This is the info off their site regarding their vista update. It has worked on my new laptop.
However, the VN-3100PC is not compatible with anything that runs 64 bit.The following is the url and the info regarding Vista Compatibility.

This download updates the Digital Wave Player software bundled with Olympus VN-*PC series digital voice recorders from version 2.1.1 to 2.1.4. It enables Digital Wave Player versions 2.0 and later to run on Windows Vista systems

The answer is all in the serial number you use to install the DSS player!

Look carefully and you will see the recorder disk has in my case an [E] printed above the install serial number and the transcription pedal has [T]

Install the same disk with the E the driver is there, the control in Control Panel is there, but the foot switch does not work with the software. Put in the serial number with the [T] and foot switch works first time!

If you uninstall the play and then reinstall with the [T] serial number you do not need to reboot or even unplug the foot switch from the USB.

Bingo
