Thanks for posting! We’ll try to help.
VBScript is a default component built into Windows, Vbscript is a common requirement among installers, but it can get disabled or broken. That can get in the way of drivers for products like the UGA-2K-A http://plugable.com/products/uga-2k-a/ you have.
The most common cause of this problem is because a specific version of McAfee Antivirus was installed in the past, which redirected a key vbscript dll. Then on uninstall, it doesn’t put the real version back.
if that’s the case, running the McAfee Consumer Products Removal Tool should fix it. Do this in two steps:
Remove McAfee from Windows Programs control panel (we recommend the free Microsoft Security Essentials instead of McAfee to avoid issues like this)
Run the McAfee tool which then fixes the broken vbscript registry entry:
Once the .exe is downloaded, right click and “Run as Administrator”. You should eventually see a “Cleanup Successful” message. Reboot and re-try the program (like the DisplayLink installer) that needs vbscript.
If that doesn’t do it, there can be a few other issues and Microsoft has a “FixIt” which can resolve several of those:

(and, for background, here is the Microsoft knowledge base article this fixit comes from: http://support.microsoft.com/kb/949140)
I know this is a lot, but it’s a tricky problem – please let us know if you have any trouble (you can email firstname.lastname@example.org anytime) and we’ll do everything we can to help.
