Microstudio won't reconize Plextor CD-R PX-W4824A

[MTUSUPPORT]

As BobCox stated, you needed to Reboot at the end of the Installation.

If you did this and you still don't see the drives, then try searching for the file wnaspint.dll it should be located on your computer in the C:\Windows\System32 Directory. If you find this, then right click on it, left click Properties, left click the version Tab. Then on the bottom Left, click on Version and it should give you a number such as 1.16 or 1.20, this is the correct version.

If you have anything other than 1.20 here then delete the file and Reinstall the Microstudio, it will then upgrade the version to the latest.
