1. Choose File > Open

2. In the Look in drop-down navigate to the Paint Shop Pro folder (it's usually located under C: > Program Files > Jasc Software Inc > Paint Shop Pro) or the folder where you saved your downloaded Tube file.

3. Double click the tubes folder and find the the Tube file you downloaded (you may need to change the file type to all files, when you find it, double click the file to open it).

4. You will see an image of several items, on a transparent background. Note how many columns and rows there are (you'll need this information in a moment).

5. Choose File > Export > picture Tube.

6. Fill in the Cells Across and Cells Down (rows) that you found in Step four. The other information Paint Shop Pro will automatically change for you.

7. In the Tube Name box, fill in a name for the tube (the filename only, not the extension, as it is automatically entered for you).

8. Click OK.

9. Click the picture Tube brush. From the control window you can find the tube you just installed.
