If you've tried to install PSM Studio in Windows 8 RTM x64 you've probably found by now that the drivers for the Vita fail to install because they are not code-signed. Windows 8 requires all drivers to be code-signed and it is a PITA to disable that requirement. Because of this, I have signed the required drivers for my personal use and I'm making them available until either a fix is available or I'm asked to take the link down (I have no idea if it's okay to do this or not).
They are available here:

Download the zip file, right-click and go to Properties, and click Unblock.
Extract the files from the zip, right-click on the .inf file, and click Install.
You may be prompted to confirm the installation.
P.S. - I don't know if these will have any adverse effect down the road, specifically regarding uninstallation or future updates. Proceed at your own peril!
Windows 8 is currently not supported with Playstation Mobile. This is more than likely to change in the future. In the meantime however, just wanted to notify that it is upto the users to download and install these drivers at their own risk. We won't be able to provide support on any issues caused by this. This is to add to your fair warning .
It won't install i have x64 RTM Windows 8 and it still refuses to install correctly. I tried right clicking it after extracting to my documents along with the security file and selecting install, but it replies with an error message stating "The INF file you have selected does not support this method of installation" so I went to device manager and tried to install it to " Ps Vita Type D" this time it makes the error Chime but wont show any message and won't allow me to Confirm my selection or even hit "Open". Help?
As mshkla post before Win 8 RT it's not supported by PSM so far. Anyways you can try to see another USB inf file to figure out why is wrong.
That's odd, I'm using it currently, but maybe I didn't package it correctly or there's some environment issue I'm missing. I'll give it a shot on a clean machine later today and let you know what I find.
I tried this again on a clean VM and was able to install it. Ensure the following:
1) you're logged in as a user with admin rights
2) you're using Windows 8 x64 and not x86 (won't install on 32-bit for sure)
3) you've installed .NET 3.0 support using the Add/Remove Windows Features dialog
4) you've installed PSMStudio and it succeeded (not counting the driver install)
If you continue to run into issues, let me know and I can work with you to troubleshoot.
