I just installed that on my machine and had to change up the fix to get it to work. Installation of TrueSpeech Codec for WMP 11 – Windows Vista Business Edition The DSP codec can be installed on Vista using the following procedure: 1. Acquire tssoft32.acm and tsd32.dll (can be easily found by searching for them online) a. I found tssoft32.acm here: http://members.driverguide.com/driver/deta...p?driverid=7020 i. NOTE: just do the free sign-up, because the “series of ads” never ends!...use an alias b. I found tsd32.dll here: http://www.driverskit.com/dll/tsd32.dll/3632.html i. NOTE: they make you wait for 100 seconds hoping you’ll click on some ads while you wait…click a couple and they’ll make some $$$ 2. Copy both files to the “C:\Windows\System32” folder a. Note: If tssoft32.acm is present, rename it tssoft32_old.acm before you copy the new version to the folder 3. Place tssoft32.acm and tsd32.dll into the Windows\System32 directory 4. Create the following registry entry: a. Navigate to the following folder: KEY_LOCAL_MACHINE>Software\Microsoft\Windows NT\CurrentVersion\Drivers32 b. When inside the Drivers 32 folder, right-click and select New > String Value c. Name it “msacm.trspch” d. Right-click the new “msacm.trspch” and click “Modify” e. Set REG_SZ value to: “tssoft32.acm” f. No need to reboot, just close regedit g. The registry setting should look like this: http://farm2.static.flickr.com/1076/958046988_5cb082830a.jpg 5. You can verify that it is installed by opening WMP 11 and under the Help menu, clicking on “About Windows Media Player” and then “Technical Support Information”. A webpage will open listing all the codecs installed. If tssoft32.acm is listed, you’re set! If not, I am sorry, but I cannot help you :-( Caution: Do not edit the registry unless You already know what you're doing.
