There's a readme.txt file included in the script, did you try following those instructions?

Here's a recap of the important parts of that file:

/*======================================================================*\
|| 3. First Time Installation / Upgrade                                 ||
\*======================================================================*/

1. Upload all files from the "upload" folder to your forums directory.

2. CHMOD the following folders to 0777
	/core/packages/dbtechthanks/vbactivity_type

3. In AdminCP -> Plugins & Products -> Manage Products -> Add/Import Product
in the "OR import the XML file from your server" put

./packages/dbtechthanks/xml/product_dbtechthanks.xml

4. Configure your Usergroup settings by clicking "Manage Buttons" under 
"DBTech - Post Thanks" in your AdminCP navigation menu, then
editing each button and setting your usergroup permissions from there.
