Error message when installing wireless printer

I had a technician remote into my computer, and he had the following to say about the issue (see below in blue). I believe it is a reputable shop, just not sure they know how to fix this particular problem:

I understand what he is saying, but we have a Toshiba computer, and I was able to download he software from HP with no problem on that computer, so I don't see why the same download would give me an error on a different computer, unless the problem is with the computer itself. I just want to make sure I am not spending money needlessly to fix this problem.

Thanks.

The HP printer software has a bug that prevents it from installing correctly. The software gets extracted to a temporary directory, and then it is supposed to install from there.
HOWEVER, the software's parameters expect it to extract to and install from a folder "7zS458b". The folder it extracts to is named something else. I renamed the folder to "7zS458b", and the software began installing. Once the software was nearly finished, the install failed with a similar message to before. The HP program then quit, removed itself, and rebooted the computer. It kicked me out as a result, and naturally I cannot connect again.

After some research other people are also having this trouble. HP really makes sh*#y software packages; I have seen troubles with them far more than any other printer manufacturer.{Unquote}
